Hi, I could imagine a good result in using hardlinks between backups of DIFFERENT servers. We backup a lot of Linux servers on one backup server, and all these linux installation share the same distribution files. So "de-duping" these vaults could really decrease the used disk space!
@Issac: which hardlink command do you use? Best regards, Dirk Melchers.
