since a couple of weeks, we have one VBR 188.8.131.521 backup system, which serves as a backup System for 2 different customers. Both customers have 11 VMs in their B2D-jobs, which result in the following deduplicated disk-usage-capacity in the customer's respective backup-repository ...
Customer A = 4.63TB used capacity in Customer's A backup repository
Customer B = 2.51TB used capacity in Customer's B backup repository
VBR 184.108.40.2061 works like a charm, the only thing I would like to discuss, is the fact, that VBR doesn't seem to use the full capacity of an LTO6 tape media, see here ...
As you can see here, lots of space is unused on LTO6 tape media?
Also Customer B uses 2 LTO6 tape media. Ok, in the meantime 2.51TB is used, so that 2 LTO6 tape medias would be necessary anyway, because the deduplicated B2D data is already compressed and we don't compress data on tape again.
What's the reason?
