I need to buy a good imaging program and also want one thats intuitive
and
used widely in the work place etc.. Would Norton or Acronis do the job
and if
so which is better more widely used by techy pips?
Be aware that if you are thinking of the Home version of Acronis True
Image, it lacks several features which are considered mandatory even for
a single-workstation backup. It doesn't support Volume Shadow Copy.
Although the Volume Shadow Service (VSS) may be enabled or automatic, TI
Home won't use it. That means during the backup that inuse files cannot
be backed up because they are locked. It also means that during the
lengthy backup time that the files can change so what gets saved are
files that are out of sync with each other.
For a logical file backup program, Acronis is not a good choice. Even
the NT Backup program included in Windows supports VSS. Rather than
provide the customary grandfather-father-son expiration scheme for
backups (by using catalogs of the backups), TI Home instead relies on
defining a max disk space quota for the backup location (which the user
must configure separately); otherwise, TI Home will just keep adding
more backup files until all the disk space gets consumed. This use of
disk quota by its backup files means that incrementals and differentials
that are no longer applicable after a full backup will remain in the
backup location until that backup location gets bigger than what the
user configured for its maximum disk consumption. Also, disk quota
doesn't apply to their Secure Zone which will simply fill up and run out
of space until you delete the old and non-applicable backup files.
Supposedly TI Home has priority levels for the backups but I found that
anything other than Low results in a locked up system (or so slow that
it can take 10 to 15 minutes just to get Task Manager to show up). The
CPU usage is at 100% but the TrueImageService.exe process is at the
selected priority so it is supposed cooperate with other processes;
however, the program floods the data bus with backup traffic which
effectively locks up the host.
Back when I used Ghost (pre-DriveImage version), it defaulted to saving
logical partition images. That is, it read the files through the file
system and that's what it put in the image file. That means you really
don't end up restoring exactly what was there before. To get exactly
what you had before, you need to save a *phsyical* partition image and
that means reading the sectors. A feature may be the file system gets
used to determine which sectors are not currently allocated by the OS in
that partition to reduce the number of sectors in the physical image
file (to reduce the size of the image file). With Ghost, you had to
specify a command-line parameter to force it to perform a physical
image. DriveImage did physical images (with reading through a
recognized file system to exclude the unused sectors) so I suspect
that's what Ghost does now. With Acronis True Image Home, the only way
a physical image gets saved is if the file system is corrupted or it
can't recognize the file system to read the files through it. Acronis
will always do a logical image and there is no option to force it to
save a physical image. Also, any image program that doesn't force a
reboot of the OS to ensure the partition being imaged is in stasis might
end up with an image that isn't exactly what was there when the imaging
process started (since VSS can't be used for a static snapshot of the
files since sectors are being read, not files). Acronis TI Home doesn't
save physical images and it can't use VSS for logical file backups.
The only reason why I bother to leave TI Home installed is because it is
now my only partition imaging program as my old version of DriveImage
stopped working. DriveImage was made by Powerquest that got bought out
by Symantec who then replaced their old Ghost engine with the one in
DriveImage.
Before getting commercialware, you might want to visit their forums.
For Acronis True Image, visit
http://www.wilderssecurity.com/forumdisplay.php?f=65. Just remember
that most posts will be negative since users are going there to get help
with the product, not to extol its virtues.
For the $30 that I paid for TI Home, I pretty much got a personal backup
program that only does logical backups (and only does logical imaging).
However, because it doesn't support VSS and because I'm not going to
waste even more money to buy their Workstation or Server versions that
do support VSS, I was thinking of reverting to NT Backup for the logical
file backups because I can configure it to overwrite the backup files in
a grandfather-father-son scheme, it supports VSS, and my host doesn't
lockup during the backups; however, the big flaw with NT Backup is that
it doesn't itself support compression. If the [tape] drive supports
hardware-based compression then it will enable that function but it will
not compress when writing the backup file to a hard drive. Actually I
had the Veritas Backup Exec Desktop program which is the uncrippled
version of NT Backup. Veritas sold it to StompInc which renamed it to
Backup MyPC which became Migos Software and is now called PC Backup.
That backup program supported everything in NT Backup supports but also
would compress to any destination media and supported more media types.
Alas, Backup Exec Desktop stopped working a year ago so I uninstalled it
and now I can't find the install CD to retry it.
Eventually I'll get Ghost and dump True Image Home to give me the
ability to save *physical* images. For logical file backups, I am
unimpressed with True Image Home (for more money, the Workstation
version is probably better if only because Acronis claims that it
supports VSS). Hell, Comodo Backup seems to have more options and is
free (but I haven't done an in-depth trial of it yet). For images, and
because TI Home only does logical imaging, I'll have to find something
else that saves physical images.
Learn and burn.
