Nice. Especially for clients where you're only really worried about the
data on the machine. But using "systemstate" may not allow you to do a
true bare metal restore of a windows box. For a bare metal restore
(servers, etc), I'd recommend doing an ASR backup of servers
periodically in ADDITION to the backuppc backups. That way you can use
the ASR restore during the Windows install process to get back to a
stable system then use backuppc to restore the newest incremental.
Something like
ntbackup.exe asrbackup /J "Full ASR Backup of C" /f "D:\C-asr.bkf" /V:yes
works ("asrbackup" backups also use VSS internally and are a superset of
"systemstate" backups). Drop this disk image on D: or some other FAT32
partition and have backuppc pick it up. Since the resulting backup file
is a disk image, you'll want to keep C: as small as possible. Ideally
just the OS, or the OS plus your core applications. Store everything
else in DFS or on another local partition. For data integrity, make D: a
separate physical disk if you can.
For a bare-metal restore, you simply use the newest image on D:, or in
the event it's not available, copy it onto D: via your favorite occult
method (Knoppix would work well, but since D: is FAT32, there are other
options).
Hope someone finds this useful!
