Thank you all for your suggestions!
I have set up several backup copy jobs which have been running for several months. In this case, it is a bi-monthly archiving, and thus every 60 days veeam does a copy to the archiving repository. I planned to only create full backup copies, however this is what i have:
1. Task setting: does a copy every 60 days
2. I set keeping 6 restore points (since it is bi-monthly and i keep the backup for a year). Compact Full is checked.
3. However on the archiving repository, I've got incremental files. I thought I would be able to get all full backup files copied over. Am I setting up something wrong here?
