Tom, thanks for your input. You brought up several key issues with how we've been archiving.
[Tom Goldberg] "First, the CatDV plugin does not deal with spanned tapes aka Multiple Volumes."
We have been trying to add media from multiple volumes.
[Tom Goldberg] "In order to restore files with CatDV's plugin, they must already have been restored to the VTAPE by the user first."
I simply followed the instructions from Matt Stamos on this YouTube video where there is no manual intervention:
We have been using LTFS but currently are working with a tape that somehow became a .tar format. We have over a TB of "space lost". What do you make of that?
[Tom Goldberg] "have you contacted our tech support? We can help you through some of these issues. What version is your Cache-A (you should be at v2.1.15)?"
We have contacted tech support. Rolf actually gave us a helpful response today which we haven't had a chance to test since we're also having an unrelated archive issue with another company and we've been working with that all day. I will give you an update as to if this fixed some of our problems.
It also looks like we have an old version as we're operating on v2.0.22. I'll update that and see if that helps. Hopefully we will have time to run some test and devote all of our attention to this so I can give a detailed update by the end of week.
