Retention Policy for Weekly Backups

Previous page Next page Print this Topic

Table of contents

Veeam Backup & Replication repeats the weekly backup cycle until the number of weekly backups allowed by the retention policy is exceeded. After that, Veeam Backup & Replication removes the earliest weekly full backup from the target backup repository to make room for the most recent weekly full backup.

When deleting obsolete weekly backups, Veeam Backup & Replication considers weekly intervals, not separate backup files. For this reason, in some situations the target backup repository may contain a greater number of weekly backups than specified in the GFS retention policy scheme.

For example, you have selected to retain 4 weekly backups. The weekly backup is scheduled on Sunday. Right after the first weekly backup is created, you change the weekly backup schedule and schedule the weekly backup on Thursday. As a result, during the first week Veeam Backup & Replication will create two weekly backups. At the end of the month you will have 5 weekly backups on the target backup repository:

One weekly backup created on Sunday
Four weekly backups created on Thursday

On the 5th week, Veeam Backup & Replication will add a new weekly backup to the target backup repository. At the same time, it will remove all backups that were created on the first week – Sunday backup and Thursday backup.




One and the same full backup can be marked as weekly, monthly, quarterly and/or yearly.  When transforming weekly, monthly, quarterly and yearly backup chains, Veeam Backup & Replication checks the flags set for the full backup file. If the full backup file belongs to some other retention policy tier and must be retained on the target backup repository, such backup file will not be removed.
