Hello everyone
I am preparing to implement Bacula
on one of the servers I look after, but being new to the Bacula subject
I would like to ask for some advisory from users more experienced.
The server I mean to run Bacula on is Debian Wheezy-based and serves
as a host to several LVM-based Xen virtual machines running Wheezy as
well. Some of the VMs are database servers (mainly PostgreSQL). The
intended Bacula version is 5.2.6, available in Wheezy repositories.
My first question concerns where it is more advisable to place
Bacula daemons: on the host system (and back up using LVM snapshots) or
in the virtual machines themselves? I guess it's easier to ensure data
consistency using LVM snapshots but I am afraid it would be much harder
to restore the machine in this way so I am inclined to install Bacula in
the VMs. However, wisdom comes from experience, so I ask you, the more
seasoned users: which of the ways is less likely to give me headaches
and what are possible 'gotchas' in each one? My intended use of Bacula
is being able to restore a failed VM back up quickly in case of a
disaster, rather than restoring single files. Any recommendations would
be more than welcome.
