We plan to use two tape libraries (one 48 slot and one smaller 8 slot). The 48 slot will be used to write data (~50+TB/annum), once the data has been written and cartridges become full we plan to remove the cartridges and put them in an offline storage facility.
Once some data is required, we plan to take the cartridge and put it into the smaller tape library to retrieve the data.
Will the other tape library "know" what data is stored in the tape? Do tape's store information about the files that are stored in them as well?
We plan to use LTO-5 (but not with LTFS).
