According to the manual,
cbbackup --mode accu does a:
Perform a cumulative incremental backup, which backs up all changes since the last full backup
However, it seems to backup all changes since the last full backup or previous accumulative backup.
Our intention was to run a weekly full backup and daily accumulative backups, so a restore would only require to restore the last full plus last accumulative backup. But the way it is working, an accumulative backup is effectively the same as incremental backups, when used in our backup scheme.
When first doing several incremental backups, an accumulated backup does include all changes contained in these incrementals, starting from the last full/accumulative backup.
Is this behaviour how it was intended to work?
