Hello

I have a Netstor NS722TB3 Thunderbolt 3 host case for 2 IBM 7HS drives. I use the Ltfssde linux drivers and manage the copies using the mucommander app.

I am backing up Hard Drive archives to tape using a multi slot docking station.

To gain time, I had the brilliant idea to open 2 instances of mucommander, one for each drive mount point and copy a different hard drive to each tape (not 2 hard drives to the same tape at the same time). I figured that my PC could handle the 2 separate flows of data. I did not notice any particular difficulties during the copies, even if the copy times did fluctuate sometimes quite radically.

Now, I want a second back up of each LTO on another one, so I am copying from a source drive to a slave drive. But the source drive seems to be so "fragmented" that the copy is taking for ever and I wonder if I will have a tape left at the end of it. I thought that the slave would blindly copy the source as is ... but that does not seem to be the case. Could this source fragmentation come from me doing multiple copies at the same time?

I cannot get the ltfs_order_copy script to work. I also like a copy GUI so does anyone know if there is a LTFS linux copying "system" that can manage the tapes better than I am. I have tried to get YATM https://github.com/samuelncui/yatm to work but without success (and the project looks a little dead).
