hi,
I have been wanting to deploy Bacula onto live Production environment.
I have been checking/working out the basic features of Bacula and they seem
to match my requirements to a great extent.
The scenario looks like :
I am looking to backup data on clients laptops/desktops. These machines run
primarily Windows (XP/2000). I am looking to install WinBacula out here. The
Bacula-Director would run on a Linux Server running RedHatEL 3. Initially, the
total number of clients is about 15. But this number will definitely grow, real
quick.
However, I have some things playing up in my head like :
(1) Bacula can backup data in three ways i.e. full, incremental or deferential.
If any file is modified, the complete file will be backed-up. If we take an
example of a .PST file (Microsoft Outlook Mail File) which is normally of
300-400mb in size, is updated, the full file will be backed-up over the wire. If
we consider 10 clients, than it would backup around 3-4gb at the same instant.
Would this not increase data traffic considerably over the wire ? If this is
true, is there any way to reduce/control this ?
You can't control the amount of data to be transferred except for using
compression, but you can control the bandwith needed by controlling how
many backups will run simultaneously.
(2) Is there any limit on the number of users that Bacula can support ?
None is implemented, but there are of course limits set by your
hardware. Especially the catalog datanase can be a bottleneck.
(2) I have read about Bacula's support for VSS, which allows to backup files
that are currently being used by an application. Can i use this feature with
Bacula version 1.36.3 ? I remember having read that version 1.37 supports it. i
need to use this feature. Is 1.37 stable enough to deploy in a live production
environment ?
Well, you need 1.37, and I think that 1.37.40 (or above) should be
stable enough. True, I would still consider it a bug-hunting version,
but basically it's working here and in other locations stable for quite
some time now.
Note that, as far as I know, VSS snapshots are not supported by windows
2000.
I c immense potential with Bacula. So, I am pushing for Bacula as against other
Commercial Network backup solutions out here. It would be great if somebody can
help me clear out my doubts. Thanx !
You're on the right track :-)
Seriously, though, there are things that Bacula can't do and which other
software does, but deciding what you want is always up to you. If Bacula
delivers what you need, you should definitely give it a try.
