Veeam Office 365 Snapshot-based retention


Userlevel 3

Hi,

 

I would like to confirm if the Snapshot-based retention keep the full backup and only delete the incremental snapshots according to the retention policy (years, days, etc.). I need to do an incremental backup job like VBR, to keep only 2 months of incrementals.

 

Thanks,

 

Omar De Souza.

Hi @ODeSouza -

Not entirely sure the question you’re asking, but if you have a backup copy job and using GFR retention, you can go into your ‘Backups’ section in the VBR Console, rt-click the Backup/Copy Job > Properties, then you can see what the backup file type is - (M)onthly, (Y)early, (W)eekly, etc.

Hope that helps.

Hi @ODeSouza,

 

VBM365 functions differently to VBR. Whereas VBR works with full and incremental files, instead VBM365 utilises a database so each item is backed up once, it’s a lot more space efficient for item based workloads such as this.

 

Some good reading:

If you’re planning on using cache + object storage: https://helpcenter.veeam.com/docs/vbo365/guide/vbo_osr.html?ver=60

If you’re planning on using traditional storage: https://helpcenter.veeam.com/docs/vbo365/guide/vbo_backup_repositories.html?ver=60

 

In summary though, your snapshot retention will keep the item for your database for as long as it exists in production + your retention period.

If in the database of the backup VBM365 we’ll have all the email messages as they are in the production O365 + my retention period, that means if we configure a retention policy of 60 days and today somebody delete an email message received in 2020, we can recover it from the backup, right?

correct :) item level is based on when the content was created/modified, whereas you said you’re using snapshot which is based on the time of the backup.
