Title
How to manually identify backup file of a DC based on collection name and remove anything older than retention time? -
Description
Sometimes backup older than the retention policy don’t get removed automatically. Instead, a manual cleanup is required to delete older backups than retention policy. -
Cause
The retention policy on a collection only works for this collection. So even if you have older backups, they will not be deleted if they were created by another collection. -
Resolution
If you need to manually remove specific backups, you can do so using the PowerShell cmdlets:
Get-RMADBackup (with some filtering) and Remove-RMADBackup.
For example, to delete backups older than 7 days (regardless of collection), you can type something like this:
$date = (Get-Date).AddDays(-7)
Get-RMADBackup -MaxDate $date | Remove-RMADBackup -Delete $true -Confirm:$false
The retention policies are bound to a collection. So, to run a script on backups from a collection, you need to specify the collection ID:
$date = (Get-Date).AddDays(-7)
Get-RMADBackup -CollectionId [id number here] -MaxDate $date | Remove-RMADBackup -Delete $true -Confirm:$false
To get the collection ID, you can run the Get-RMADCollection cmdlet:
Get-RMADCollection | select Id, Name, ConsoleSideRetentionPolicyEnabled, ConsoleSideRetentionPolicyCount, AgentSideRetentionPolicyEnabled, AgentSideRetentionPolicyCount
