Hi,
I'm able to backup Windows 2012 server with deduplication enabled. My
bacula server is also centos, bacula version 9.6.5 (on client and
server). I have tested only individual file restores but it always
worked for me. Backup is very small (54 GB for app. 700 GB raw data).
I'm not sure how bacula manages to backup and encrypt deduplicated
amount (I would expect that there will be 700 GB on the wire). I'm
having some performance problems (see thread
performance&design&configuration challenges).
I'm at the the end of testing bacula sw, so I'm not an experienced user.
I would also appreciate if someone confirms, that this should work. If
it helps, there is log from my last backup.
Kind regards,
Ziga

So, there is no solution? Bacula can't backup such clients?
I know nothing about windows filesystem deduplication capabilities,
but I assume to properly read contents of these files a standard win32
BackupRead() dedicated to backup function is not sufficient and
requires special handling.
I do not know if this special handling is available in Bacula, but as
this is not my area of interests in Bacula my answer could be incomplete.
