My repository shows some odd dates for full backups for several of my VMs. It appears as though only incremental backups are being run.
Running a Backup Task report does indeed show that only Incremental backups have been running for several weeks, well beyond the Threshold count.
Disable or Remove the current backup job and create a new one. Since retention is job specific this will cause vRanger to start a new Full/Incremental cycle. The save points from the previous backup job will need to be removed manually.
