Even longer than 60-90 long chains will be 100% reliable if you use Surebackup, but the restore can take more time.

Depends on your needs and capabilities. I would say, once a day is perfect, once a week is good.
redhorse wrote:These are about 30 VMs, so what is the recommended way to configure a SureBackup Job for all these machines?
I would suggest to group VMs for surebackup verification based on their SLA, application or installed OS.
redhorse wrote:Instead of using forever incremental I can use a regular forward incremental, is it sufficient to start an active full once a month and a synthetic full once a week with transforming previous restore points to reverse incremental?
It`s fully described in the thread above, please take a look.
redhorse wrote:In both cases I have to move at least one full backup to tape once a week and nice to have the increments during the week, is that possible in these scenarios?
It`s possible with both scenarios, but in my opinion, the least resource-consuming solution is to schedule a source backup job to run weekly full backups just before, backup-to-tape job run.
