Data Management for VMware Tanzu uses an internal vPostgres database to keep track of Provider state. You configure the object storage repository and bucket in which DMS stores backups of this database by setting the Provider Backup Repo.

Note: Recovering a Provider VM requires that you have configured the Provider Backup Repo.

The Provider Backup Repo requires a minimum of 15 GB of available space.

When you configure a Provider Backup Repo, Data Management for VMware Tanzu records the transaction logs every one hour. Additionally, DMS takes a full backup of the internal vPostgres database every 7 days and takes an incremental backup every 12 hours until the next weekly cycle. The backups have a retention policy of 8 days; DMS will automatically delete a backup when it exceeds this age. Thus, configuring Provider backup settings enables quick recovery of Provider data.

DMS stores the Provider backups in a folder named provider-backups-<node-id> in the Provider Backup Repo bucket that you configure. The full and incremental backup files use the following naming formats:

yyyy-mm-dd-hh-mm-full-id-<database-instance-name>

And

yyyy-mm-dd-hh-mm-inc-id-<database-instance-name>

Note: Data Management for VMware Tanzu does not manage the Provider backup files; when you configure a Provider Backup Repo, you are responsible for deleting any backups that you no longer require directly from S3.
