Vault snapshots automation "retain" parameter

should the “retain” parameter in snapshots-auto endpoint delete snapshots ?

  • retain (integer: 1) - How many snapshots are to be kept; when writing a snapshot, if there are more snapshots already stored than this number, the oldest ones will be deleted.

I was trying to retain only 3 snapshots in an s3 bucket , but this number was exceeded and none of the old snapshots where deleted ?
is that an expected behavior ?

Vault is not going to delete older backups from S3. For that you have to setup a S3 lifecycle rule in that folder. While in the folder, click Management and “Create lifecycle rule”.

We have an internal issue that suggests that retain with S3 doesn’t work properly when path_prefix=/.

I recommend when you have issues with Enterprise features you go through the usual support channels, as they aren’t tracked in our public Github repo.
