Copy Job: Warning Message
"Your service provider has implemented backup files protection against deletion by an insider for this cloud repository. To protect against advanced attack vectors, we recommend that you configure your cloud backup jobs to keep multiple full backups on disk (as opposed to forever-incremental chain with a single full backup"

Cause

You may encounter the issue in the following cases:
If the tenant plans to create off-site backups with a backup copy job, they should enable GFS retention settings in the job properties. This way, Veeam Backup & Replication will be able to protect backups created with the job against an attack when a hacker reduces the job's retention policy and creates a few incremental backups to remove backed-up data from the backup chain.

With GFS retention settings enabled, the backup chain will contain a sequence of full backups that will not merge according to a retention policy. After such a backup is moved to the "recycle bin", the tenant will be able to use it for data restore.

If the tenant does not enable GFS retention settings for the backup copy job, the job will complete with a warning. In the job statistics window, Veeam Backup & Replication will display a notification advising to use the GFS retention scheme for the job. Note that the warning is displayed only if the tenant backup server runs Veeam Backup & Replication 9.5 Update 3 or later. In earlier versions of Veeam Backup & Replication, the warning will not be displayed, and the backup copy job will complete with the Success status.
