Thanks MK, Bruno,

"Checkpoints also happen on volume changes. This means that when a volume 
is full, or the backup has to switch to writing to another volume for some 
other reason, a checkpoint is triggered saving what has been written to 
that volume."

This sounds like what I want to achieve, so I will want to enable this.

"Based on the Checkpoints Feature, a resume of cancelled or broken 
Backupjobs is conceivable in the future"

A bit of a pain that one cannot yet resume a job which has failed from the 
point at which the checkpoint was created... Presumably this means a full 
new backup will need to be taken across all tapes. If this happened in the 
middle of a tape I would understand, as trying to get back to the correct 
position on the same tape could be a pain, but if it happens when adding a 
new tape (such as the new tape being bad overall and failing immediately) 
this could be a bit of a pain.

Thanks
