Is there any point to keep the incremental backups that are older than the oldest full backup.
When zimbra deletes the backups that are one month old it will delete the full backup one day and then delete the incremental backups for the next few days and so on. However, after the full backup is deleted, the 6 days of incremental backups until the next full backup are useless right?
