1) Where are my GRBackPro backup
software options saved?
GRBackPro automatically stores the
entire program options into a text file that, by default, is named
GRBakPro.grb if nothing was specified in the command line.
configuration file is very similar to a Windows .ini file and is
constantly updated by the program itself without your intervention
(i.e., you don't have to remember to save it). Any time you want to
start the program, all you have to do is double click over the file
GRBakPro.grb. When the program opens, you can quickly run your
backup by clicking the Backup button. There's no need to choose a
session first in this case because the program remembers the last
one you have used.
2) How can I include or exclude some files from my
GRBackPro backup software settings?
When you add or edit a backup Job you
can define in the Skip folders: edit box the names of the folders
you want to skip. You cannot place here full path names but only
folder names (as for example Windows or System). To specify the
folder names you can employ the well-known MS-DOS wild characters
('*' and '?') to represent more matching files. In particular the *
character means all letters or sequence of letters, while the '?'
character means one letter.
3) Is it possible to store
folders and path information in Zip files?
GRBackPro fully supports and effectively
re-creates directory structure outline many levels deep in Zip files
if you enable the Build a single Zip archive with stored path names
(see the Adv. Backup tab) feature. This feature, however, will make
your backup run more slowly because there is a single big zip file
to manage and, moreover, some Zip file viewers may not display
folders inside the Zip files correctly. Windows, starting from XP,
support folders in Zip files and shows them just fine. This option
lets you have a single compressed file or a single destination
folder where to copy all your source files. We suggest you to
experiment with the destination layout option of the Backup tab to
see how many other possibilities you have.
4) Why must the destination
directory start with "Bak_sd"?
This root folder (that you can create or
not depending on the Destination path layout options of the Backup
tab) is needed by the restore procedure in order to know from which
source drive a backup archive is coming. The other purpose of this
folder is to have a well-defined means to identify the root folder
of any backup archive (if you do not use any additional path name in
your destination path layout). For example, if you back up one drive
into another and vice versa when the second backup starts it will
backup also the directory created by the first backup run if there
is no way to distinguish it. If you do the backup of the previous
backup you will waste useful destination disk space. GRBackPro can
automatically skip all the directories that start with the string
"Bak". If you enable the option Skip standard folder names:
Bak*;Tmp;Temp;Recycle*;System Vol* in the Options tab the program
will skip these commonly used directory names that do not contain
useful data. The folder skip match can be case insensitive if you
disable the option: Make skip folders options case sensitive. By
naming your backup root folder with a starting Bak string you will
not back up any folder that contains backup archives.
5) After I install a program
update do I need to install the license again?
If you install a new version over an
existing one then your settings and license will be preserved. In
any case, for safety, we suggest that you store somewhere both the
latest version installation package along with your license
information so that in case you lose the program you can quickly
install it again. If you want to save the program settings you can
also put in the same destination the file GRBakPro.grb. If you have
definitely lost your license information you can email your user
name and email or a copy of your order to our support team so that
we can locate your record in our database and send you the license
6) When I install a Site license
do I have to install it on every PC of my company?
Yes, the license needs to be installed
on every PC where you have installed the program. If you order our
surface mailed latest version CD-ROM both the latest version and
your Site license will be installed in a single step.
7) Should I have a main hard
drive failure, what would need to be loaded on the new drive to
accomplish a complete Restore?
The safest way to restore your drive is
to install Windows. After your Windows setup is complete you can
install GRBakPro and then run your restore. Another solution is to
employ the WinPE DVD (Windows Pre-installation Environment). This is
a bootable system DVD that lets you see your current NTFS and FAT
hard disk drives content and run some system check utilities on
them. This can be a solution if your system is only corrupted (i.e.,
you do not have an hardware failure) or if you simply want to
restore all your files to your new hard disk drive or if you want to
restore an older version of your registry.
8) Why, with compression level
set to zero, does GRBackPro continue to create ZIP archive files ?
Is it still zipping the files?
GRBackPro always creates a ZIP archive
if compression is enabled. If the compression level is 0 it will
store the files in the ZIP archive (i.e., no compression of the data
will take place). In this way the source files are always packaged
together. If you want a simple copy of your files, you must
completely disable the compression.
9) Can GRBackPro back up a file
that is opened by another application?
Yes. GRBackPro starting from version 7
supports Windows Volume Shadow Service (VSS) and if this service is
active on your system then any locked or system file can be backed
up without problem. If the Windows Shadow Copy service is not active
then only files not locked and opened for not-exclusive write can be
backed up. An example of a file opened in exclusive mode is the
Outlook database file .pst. You must skip these files or schedule
your backup when these files are closed (over night for example).
The virtual memory or swap files are automatically skipped by
10) Does GRBackPro ask me for
another removable media if the first one becomes full?
Yes. You will have the option to insert
another disk media when the previous one becomes full. There are,
however, a few notes about this process. If compression is disabled,
the program is not able to put on the destination disk a file that
is bigger that the destination disk itself (i.e., it cannot split
that file in smaller pieces). This limitation is not present if you
enable the zip compression. The program can create independent
destination disks that together form your backup archive. This means
that if you lose a single disk of your backup set you will not lose
the complete backup (as normally happens when you spilt your files
over multiple disks) but you only lose that single disk and you will
be able to restore all other files. Another note is about the backup
mode. If your backup is on multiple disks you cannot safely run a
backup update because it can be that your destination disk is
already almost full and cannot store any updated file whose new size
is now bigger then before. In other words, if your backup requires
many destination disks you need to run FULL backups only.
11) Can I synchronize my source
files with the stored backup archive with GRBackPro?
Yes. There is a special option both in
the Backup and in the Restore tabs that lets you delete any source
or destination file that no longer exists. In case of Restore, every
time a source file is found that does not exist in the backup
archive, a delete confirmation dialog box will appear allowing you
to decide if the deletion is correct or not. This is a safe
12) Why, while backing up big
files, does GRBackPro takes so long to compress?
When you handle big files (normally over
100MB), the best strategy to use is to disable the compression.
Normally big files are already compressed (say for example video
files) and thus spending time to compress them further will give you
no saving on space and only loses time. You can disable the
compression on a single Job by checking the Disable Compression
(force copy only) option in your Job from the Add Job dialog box.
13) I have lost my Job list. How
can I restore my backup archives with GRBackPro?
If you do not disable the Save the
backup definition file option in the Options tab then your backup
settings included the Job list will be copied to the destination
disk. You can manually restore this file into the current user
Application Data / GRSoftware / GRBakPro folder and then run
GRBackPro. If you no longer have the backup configuration file then,
from the Restore tab, you can select from the Source group the
Folder option and press the Browse button to specify the path name
where your backup archives reside. In this case you must also
specify the Destination of the Restore operation to a specified
Folder because the program is no longer able to automatically
rebuild the original source path.
14) I want to start my GRBackPro
overnight. How can I disable any error dialog box that stop the
backup procedure in case of errors?
In order to avoid any dialog box message
that stops the backup process you must uncheck the Attended backup
(Stop & Prompt for errors and confirmations) option in the Options
tab. In this way any error message will be only stored into the log
file and the backup will not stop.
15) I want my server
backup run even if no user is logged on. How can I accomplish this?
In order to automatically run your
backup when no user is logged on, then you need to install the
program "as a service" and add an event in the Schedule tab in order
to have your backup start automatically. If the program is already
installed you need to install it again as a service. When the
program is running as a service you will get the Service Options
enabled in the Adv. Backup tab. With these options you will be able
to define the backup user credentials. This is a required step in
order to allow the program to reach your network resources when no
user is logged on. If, instead, there is a logged on user then
GRBackPro will use the current user credentials to run any backup.
16) I experience read and write
errors backing up to a USB hard drive connected to my computer
through a USB hub. What can I do to solve this problem?
The symptoms will vary, and may often
appear as numerous "read" and/or "write" errors. Windows may easily
read and write a few files with no problem, so the problem doesn't
normally appear. But in some cases, especially when the hub uses a
small switching power supply, the reserve capacity of the supply is
drained by the heavy load and the supply voltage is no longer
regulated properly. This has been observed on one hub whose supply
could not maintain regulated power under sustained disk access. The
solution was to replace the hub with one powered by a much larger
power supply with regard to power capacity. It was noticeably larger
and heavier too, since it was a traditional transformer powered
unit. Users who are considering using USB hard disks for backups
should make sure their USB ports are adequately powered to support
the disk drive. It may even be necessary to use a well-powered USB
hub instead of the computer's internal USB ports if the computer's
ports are not able to drive the disk directly.
17) Will GRBackPro back up to my
CD / DVD drive?
Yes. Writing to CD and DVD discs is
supported as long as you have some packet writing software installed
on your computer. It usually comes bundled as a part of larger
CD/DVD recording software packages and makes your CD or DVD drive
act as a standard, transparently write-enabled drive. Packet writing
software uses UDF-formatted CD and DVD discs, and allows GRBackPro
to write to your CD/DVD drive by treating it like a hard disk or a
big floppy, using the regular drive letter. Most CD/DVD writable
devices come packaged with software of this type, so you may already
have some packet writing software even if you're not aware of it.
Here are some of the tested and approved products we know of,
undoubtedly there are more:
InCD. Part of Nero Burning ROM by Ahead Software.
DirectCD / Drag To Disk. Part of Easy Media Creator by Roxio.
Drive Letter Access DLA. by Sonic.
Sometime there is no need for
packet-writing software at all. Many new CD and DVD writing devices
are being made using Mount Rainier (Mt. Rainier) technology. Mount
Rainier is a new standard being supported by Compaq, Microsoft,
Philips and Sony that provides background formatting and defect
management for storage on CD and DVD. EasyWrite is the marketing
logo for Mount Rainier compliant drives. Mount Rainier and EasyWrite
make rewritable discs far easier to use. With EasyWrite, CD and DVD
drives work in the same transparent way as a hard disk or a floppy
drive. The goal for Mount Rainier is to change the manner in which
future CD and DVD recording is done. Mount Rainier native operating
system software (like Windows Vista) is expected to format and
manage CD and DVD media, just as operating systems currently manage
other storage devices like hard disks.
18) What if GRBackPro can't back up to my
CD / DVD directly?
You can back up to your computer's hard
drive or if your computer is part of the network, you can back up to
a networked drive on another computer. But what if you want external
backups and don't have a working packet writing driver installed, or
you don't have a CD/DVD drive with integral EasyWrite support?
There are three possible workarounds for this case:
Simply cease to use CD / DVD as a direct target for
your backup operations. Set up GRBackPro to run your
scheduled events and let it create backups to your hard
drive automatically. Every week or month you can copy
the backup copies created with GRBackPro to your CD /
DVD device manually, with your favorite CD / DVD
recording software or Windows XP built-in CD / DVD
If it's really necessary to run automatic CD / DVD
backups, consider buying a good packet-writing tool. For
example, Ahead company sells its Nero Burning ROM suite
for only $50. This package includes many useful
components, including the InCD packet writing software.
We have tested Nero InCD thoroughly, and are happy to
Apart from the conservative CD and DVD writing
devices, there are a lot of alternative backup storage
devices now available, which are often better, faster,
more reliable and more affordable! If you need automatic
external backups, consider good alternatives to CD / DVD
devices. There are a lot of cheap USB flash memory
sticks available on the market today. They are fast,
easy, portable and compact and can readily handle up to
2 GB and more of data on chip. For larger quantities of
data, consider external USB hard drives as they have
much greater capacity than a single CD or DVD. After
all, CD and DVD are great for maintaining a collection
of discs, but not for regular backups. For regular
backups of critical, important data, USB flash memory
sticks (or keys) as above works the best.
19) Why does my backup
just dump everything into one folder?
Have you created a job that just copies
an entire folder and sub-folders to another hard drive and found
that your backup just dumped everything into one folder? This is
because GRBackPro has an option into the Backup tab that allows you
to insert the source folder name into the destination disk path .
This option is named JobSrc. If this option is enabled (you see the
JobSrc string in the Destination path layout forth combo box) then
the source folder name will be placed into the destination path, but
if this option is OFF (blank) then no source folder name will be
added resulting in all the source files being copied into the same
20) I keep getting the following
error message from GRBackPro: missing end zip signature. What does this mean and
how do I fix it?
This message normally appears when there is an error in one of your
zip archives. The error has corrupted your archive and the GRBackPro
compressor is trying to fix it. If this error message repeats, then
GRBackPro was not able to fix the problem. The remedy is to manually
delete the zip file that shows the error and then run another backup
to let GRBackPro re-create it. An alternative is to run a full
backup so that all zip archives are re-created.
21) Why does the
program executes a full backup when my system change to or from
daylight saving time?
The problem can be easily solved using
the option Ignore 1 hour time delay on file compare (NTFS daylight
fix) in the Options tab.
At time changes, GRBackPro can get
fooled when the source and destination file time change is made.
With this option set, GRBackPro will realize that the 1 hour
difference does not mean the file needs to be backed up again.
22) Why does GRBackPro doesn't execute a real source
file compare against the destination ones?
The function is named Verify because it doesn't
really compare files. Anyway, even if you do not zip GRBackPro will
do a complete read back of the backed up files. This means that the
file is verified as completely readable and consistent. This, of
course, will not warrant you that a bit were changed since the write
(due to a defective destination media) and in this optics you have
less protection. You must know that when the media are broken, often
(more than 90% of the times) they are no more able to read back the
file and don't simply change a bit. This is due to the hardware and
firmware of the devices that for any disk sectors add some
redundancy bits in order to correct the whole sector in case of 1-2
bit failures. The firmware also is aware of the problem and normally
signals this to the system (for hard disk using S.M.A.R.T.) that
some sectors are degrading. Optionally the hard disk is able to mark
a whole zone as BAD and relocate it on some free tracks on the disk
reserved for this scope.
If you compress your files then a CRC (Cyclic
Redundancy Check) is added and you will be warranted that no changes
happened to the compressed files. This add more safety in case of
Speaking shortly today hard disk is a very reliable
device and a real compare function is less necessary then before.
I'm not saying that the compare function it is useless! The problem
is that you are accustomed with it and it seems to you that you
cannot live without it.
23) Why does GRBackPro seem slow when
compressing files onto a networked drive?
considerable benefits in speed will be seen by compressing your
backup onto a local drive and then copying the archives onto a
network drive rather than compressing directly to the network. Your
network speed and the speed of the networked drive and CPU will have
a big impact on this issue, and we recommend you try for yourself to
see which is the fastest and most reliable method.
Enable Zip compressor, Level = nnn.
lets you compress your source files and store them in the
destination archive $backup.zip (you can change this file name using
the destination path layout option) instead of simply copying all
files to the destination path. If you enable the Zip compression,
you can define a compression Level from 0 to 9. A compression level
of 0 means that the file is not compressed but is still stored in
the compressed archive. A compression level of 9 creates the highest
amount of compression at the expense of the execution time.
tests suggest that the gain from increasing the compression level is
both variable and miniscule! On average, our test data at Level 3
compressed 47% while Level 9 compresses 49% -- but the time to get
that extra 5% increased by 40%. The default value of 3 has been
chosen because it appears to be a reasonable balance between speed
and size. Your figures may vary.
24) Can I move from Version 7 back to Version 6?
Yes, this can be done on Windows XP or
below. With Windows Vista and Windows 7 the location of the files is
quite different between v 7 and v 6 and therefore it is not possible
to make it an automatic process. You will need to run v 7, make note
of the log and grb file locations (Report, View debug logs, view log
files paths), then install v 6 and manually copy saved ANSI settings
file named GRBakPro.grba to C:\program Files\GRBakPro\GRBakPro.grb.
This is not a recommended procedure, however, as V7 works with Vista
and Windows 7 much better than V 6 does.
25) What is the difference between "Backup" (on the
bottom bar), "Restart" in the Scheduler Tab, and "Run" in the
The "Backup" button across the bottom bar will
start a backup of whichever Session is showing in the Jobs' tab.
Clicking this button has no effect on the scheduling. The "Restart"
button will change the status of the highlighted event(s) to
"Never", so that each event will start calculating it's next run
time from this moment. The "Run" button will start a backup using
the highlighted event(s) and will set the "Last Run Time" to now.
This can cause some seemingly strange scheduling. For example, if an
event is set to weekly on Monday, and on a Tuesday you click "Run",
the scheduler will set the Last Run Time to Tuesday and the next
Monday will then be skipped because the backup has been executed
this week. The best way to learn what is happening to set up a small
job and test it.
