In previous VM Backup versions only one operation could be performed on a Virtual Machine at the same time.
- If a retention policy takes quite long to complete then backups and restore operations are queued until retention is complete.
- If an Offsite Copy to Azure takes days to complete, especially for the initial backup; then backups and restore operations for that VM are queued until it is complete.
- If a Restore, File Level Restore or Boot from Backup operation is active then no backups for that Virtual Machine could take place until they are completed.
In VM Backup 7.6 these limitations have been addressed, allowing users to restore and take Offsite Copies without delaying any Backups whether scheduled or CDP.
In addition to that, now that it can run concurrently, the retention operation runs four times throughout the day in order to keep the backup repository clean.
