Archive Backup Chain

If you enable backup archiving for a backup policy, Veeam Backup for Microsoft Azure creates a new backup in an archive repository during every archive session. A sequence of backups created during a set of archive sessions makes up an archive backup chain.

Note

The forever forward incremental backup method is not implemented for Cosmos DB for PostgreSQL accounts — during every archive session, Veeam Backup for Microsoft Azure creates a full backup in the regular backup chain (that is, every incremental backup contains the full database data set).

The period of time during which Cosmos DB for PostgreSQL backups are kept in the archive backup chain is defined by retention policy settings. For details, see Cosmos DB Backup Retention.
