NDMP incremental forever.
Hi all.
My customer has a huge EMC Isilon NAS, containing 2.4 Pb of data. All is not backed up, but some folders are.
These contains typically up to 80 TB of data. A full backup will run NDMP backup to tape and take 2-3 weeks to complete, so we need to avoid full backups.
Users are filling folders when a project is finished, in order to save files to tape. RL = 5 years. The specific folder will then contain previously backed up data. So we will backup using a diff inc schedule. Users adds files and folders in a ad hoc way.
This works fine for a few days, after a FULL has run. And then it reverts to FULL and
We can see that backup level 9 has been reached, and a diff inc is previous backuplevel +1.
We want to run a diff incr forever, not having to use FULL schedules. How can we do that?
Best regards
This doc suggests that NDMP on the Isilon can be instructed to use Level=10, i.e. incremental forever:
Try passing the Level=10 to the Isilon NDMP data mover by specifying at the start of backup selection directives in the backup policy.
