Roberto,
could you give us some
more informations concerning your backup-strategy.
I’m working on
the same subject and worked out some kind of “universal backup-script”
which
uses different backup-methods,
like dd with gzip, partimage, and ntfsclone for different operating systems.
Since nearly all of our
domu have their base on LVM Storage, the process of creating a snapshot
and afterwards working
with different backup tools on the snapshot seems to be the right way.
For desaster recovery an
image created with dd and gzip works great but as stated by Paul this
kind of backup is not
the right tool for daily (file-) backup.
Do you use ntfs-3g for
mounting the snapshot or the windows file system?
What about the windows
acls on those files, is rdiff able to include them in the backup?

running Windows machines - redundancy
Hi Paul,
currently I'm trying to backup Windows machines using rdiff-backup for
incremental backups.
I mount the Windows fs in dom0 and then rdiff-backup performs the
incremental backup.
To restore a backup, just mount the Windows fs, rm all files in the
mount point, and use rdiff-backup to restore an old backup to the mounted
Windows fs.

Hi,
I know that there are a lot of tools to successfully backup windows guest
machine, using samba shares, dd, rsync etc. They all work, but they don't solve
one problem: redundancy.
In my current setup, backups are done using LVM snapshots, and rsync over the
network. The problem is that the rsync is not incremental, and every time a new
copy of the entire lv is sent to the backup server. I could mount on the Dom0
the disk of the windows guest, and send the files, but the restore process
doesn't work.
Do you know/use other method to do incremental backups for Windows machines,
that is more reliable or safer than this one?
Thanks alot.
Paul Piscuc
