Hi Timothy,
Yes, you are right, but there is another problem on my side.
The /small/ subtree of the filesystem usually contains a lot of hard
links (our backup software uses hard links to save disk space, so
expect one hard link per file per day) and using a generic tool like
tar/star or rsync that uses "stat" to scan the filesysem should be
significant slower (no test done) than a native tool like xfsdump, as
Bill in a previous email pointed out.
It seems that there isn't a right tool for this job.
Regards,
Daniele
