Our organisation uses 3rd party backup tools for our 1.7TB Vault. But there remain occasions where the OOTB Vault backup/restore is useful, e.g. for migrating Prod data to Dev/Test environment with different hostnames. A full OOTB Vault backup takes several days, so using the existing incremental backup feature is desirable. However, restoring multiple, incremental backups sequentially is a very slow process, and requires significant storage for each incremental (full database copy for each iteration). Could a cumulative/differential backup be added as an option to OOTB Vault backup/restore, so that restore operation would only be Full+LatestCumulative, rather than Full+Incremental#1+Incremental#2+Incremental#3+...... It is understood that each cumulative/differential backup would take longer to complete than an incremental, however it would be significantly quicker (copy and validate a small portion of the entire file store) than having to run a full backup (copy and validate the entire file store). The likely benefits to be realised are desirable; 1. Faster to restore than using several Incremental backups, 2. Less backup data storage accumulated, since each previous cumulative backup could be deleted, 3. After first full backup has been made, there is no further need to run full backup, which takes several days to complete for larger Vaults.
