Re: [BackupPC-users] Can $Conf{DumpPreUserCmd} and $Conf{DumpPostUserCmd} be used to s top and start Exchange Server 5.5 on a Windows NT 4.0 Server as part of a BackupPC job?
I used to backup an exchange server using BackupPC and a couple Microsoft
utilities: ntbackup and exmerge. Both of them can back up the exchange
database while exchange is running. I then used BackupPC to backup the output
of those utilities.
ntbackup creates one huge file for the exchange database. Exmerge creates a
separate pst file for each mailbox.

What that means is backups taken with very old versions of BackupPC (when file mangling was off or not implemented, prior to 1.4.0) will still be displayed correctly in the CGI interface.

Re: [BackupPC-users] Backing up a BackupPc host
I recently set up my first (and only) BackupPC server. I use Mike Rubel's rsync "snapshot" mechanism (see http://www.mikerubel.org/computers/rsync_snapshots/) to back up the entire server, including the BackupPC pool, to a local hard disk drive. I take a new snapshot on a daily basis. It looks to me like each daily snapshot is taking about 2 to 3% of the total pool space. This leads me to believe that most pool files are not changing, unless the underlying data changes. So, although I have never tried it, I would have thought rsync of the pool to a remote machine might be doable. It would need a fast network due to the large pool size. Is there a problem with my approach? Thanks for the help!

At work I've joined the CentOS 5 box running backuppc to the Windows domain. I've configured kerberos in the Apache virtual host config for the backuppc web page which gives us SSO from Windows and Linux desktops, whether they're running Firefox or IE. Pretty slick!
