Hi Bekah,
The catalog function is pretty basic to Cache-A systems – it sounds like you could use some time with the user manual which can be found on the Versions page of the UI or downloaded from here.
The system does support simple metadata tagging of folders and individual files and even your management can log in and search for filenames and metadata tags from the web interface.

Hi Rebekah,
Your Cache-A has a variety of tools for finding out about content on tapes.
The built-in catalog can be searched at any time from the File Manager page without having to bring the tape back on site.
You can also get CSV dumps (Excel readable files) of any tape’s content in a variety of formats using the tricks in this tech brief: Cache-A Catalog Export Tools
BTW Tim, any Cache-A will automatically ingest any inserted LTFS tape’s index and add it to the searchable catalog.
I hope that helps!

Hi Michael,
Sorry for the late response – I’ve been a bit busy here at Cache-A and not up on the Cow for a while.
Our support engineers recall a case like this at the beginning of the month – assuming that’s the same one, we would be willing to continue working with you on this. Please reply to our last case email to ensure we have the right case and we’ll try a few more things.
Just a note that we never see this kind of thing if the content was archived and restored with no errors – in such a case, the media was most likely in the same state when it was originally put onto tape.

You are correct Tim, LTFS does not work on LTO-4, never has, never will.
I found the release in question and it stated:
Simul-Copy harnesses advanced replication technology developed by Cache-A. It enables users to simultaneously make multiple tar or LTFS LTO-tapes copies, rather than sequential copies, at close to the same speed as a single copy. It works with Cache-A’s LTO-4, LTO-5 and latest LTO-6 generation appliances.I can understand why someone could parse that to mean we are claiming LTFS on LTO-4, but what we should have communicated is that Simul-Copy works on LTO-4 (tar only) and on LTO-5 and LTO-6 (tar or LFTS).
We apologize for any confusion created.

Any hand-held USB scanner outputs the standard ASCII values when it scans tape bar codes. Thus you should be able to use whatever you find cheaply or conveniently.
To use it, just put click your cursor into whatever field you want the data to appear, point the scanner and pull the trigger. It should work that easily.

[Tim Jones] “don’t imply that using a script is a bad thing”
Of course not, just not the most convenient route if there is a button to do the same thing.[Tim Jones] “BRU archives contain the block size information in the archive header “
So in addition to your script, for Shannon and other’s benefit, what command(s) should someone on a Linux system use to get that value?Tom Goldberg

Indeed, that should work if you are comfortable with command line operations.
[Tim Jones] “for LTFS or CA tapes, you need to remember to check for multiple partitions”
Cache-A tar tapes are aways only single partition like any tar tape. LTFS volumes are always 2 partitions, partition 0 for the file system indices, and partition 1 for the data.[Tim Jones] “so long as you know what block size the tape was created”
Cache-A block size is 300, LTFS block size is 512.…but I would never bother using that script for cloning LTFS or Cache-A tar tapes as we have a perfectly good user interface that does that for you.
The one critical piece of information you did not provide Tim, is what is the Bru block size?

[Tim Jones] “Cache-A devices are not able to clone a BRU tape (or any other tape format, for that matter)”
Cache-A devices can in fact quickly and easily clone any legal LTFS tape and Cache-A tar tapes.

Hi Shannon,
You Cache-A system supports the open formats of tar and LTFS. I’m sorry to advise that we do not read or write any proprietary tape formats.
Bru tapes can only be used with Bru software.
