Q

Slow transfer rate may be due to compression

I got information that LTO 1 tape format has 15 MBps transfer rate for backup and 7.5 MBps transfer rate for restore (half the backup transfer rate) and LTO 2 is 30 MBps (backup) and 15 MBps (restore).

Why does restore transfer rate take 2x longer than backup? Could you explain?
I wasn't aware of this but if it is true, I'd guess that it has something to do with compression. The native transfer rate for writing is probably the same as the restore rates they are quoting, but compression approximately doubles the speed. FWIW, compression estimates are just that -- estimates.
