Both are using reiserfs 3.6. The problem is that at the end of the backup, some pairs of unrelated files (usually 3 or 4), are hardlinked together. >From what I've read in rsync mailing list archives, it probably means that inode numbers are being reused while the backup is in progress. Does that look plausible to you ? And if it is, what can be done to significantly lower the probability of inode number reuse over a short time ? The backup shouldn't take over 1 hour, the server stores around 570k files, but it's only a quite low traffic IMAP server, so even with 32 bits inode numbers there's probably some room for improvement. I know a definitive answer would be to backup filesystem snapshots, but the source server isn't currently using LVM1, and as far as I know snapshots haven't been reimplemented yet for LVM2 :( Best regards, Pierre.
