Object Storage as a Backup Target • Re: SOBR Retention Policy

Hello Clbow23

Welcome to the forum.

I would like to backup my servers and retain 7 dailies on a NAS repository
...
I set the retention policy to 7 days (I understood this as how many I would like to keep on the NAS)

Please be aware, with weekly full backups and 7 days retention, there can be backups between 7-14 days on your performance tier. That's how forward incremental works.

In the "Capacity Tier" section of the SOBR setup, I configured it to move backup files older than 7 days.

I recommend to use the copy and move policy together. That way, you will have a immediate copy of the daily backups to Amazon S3. If copy is not configured, your restore point on Capacity Tier will always be 1-7 days behind. In case you got attacked by ransomware, you would need to restore from an older backup. And loosing data can be expensive.

12 weekly in AWS S3 Infrequent Access, and finally 10 years of monthly in AWS S3 Glacier
...
In the archive tier, I configured it to archive GFS backups older than 60 days.

Sounds good. Make sure that "Archive backups only if the remaining retention time is above minimal storage period" is enabled (should be by default). If disabled, your weekly backups would also be moved to S3 Glacier.

In the actual backup job, I set the retention policy to 7 days (I understood this as how many I would like to keep on the NAS), then configured GFS to keep 12 weekly and 120 monthly.

Correct. The backup job specifies the retention for each backup.

Additional recommendation:
- Consider to use immutable S3 bucket. On capacity tier, backups will be immutable according to the specified value. On Archive Tier, backups will be immutable for the entire GFS lifetime (10 years in your case). Please consider that, if you enable immutable backups on your archive tier. You need to pay Amazon 10 years or let them delete your entire Amazon account.

Best,
Fabian
