I learned somewhere that zimbra backup (zmbackup) uses hardlinks between subsequent full backups to preserve space.
However, the full backups on my server do not seem to be using hardlinks. The total space taken by each full backup is more than the previous backup. What can be done for zmbackup to use hardlinks?
I need this feature working as my backup space requirements has increased quite a bit.
