[plug] Tapes

[Andrew Furey]

(Resending on-list, sorry Bill)

Also pigz is a must for getting data to the tape fast enough to avoid
shoeshining. (At least in our case with LTO3/4 it made a huge difference…
LTO8 I couldn’t seem to get it there fast enough regardless.)

(tar -cf /dev/st0 -I pigz source, rather than tar -czf.)

It won't fit in any of my on-line machines, so the intention is to put it into the office "workshop" machine with a fast disk, stage the backup onto the disk and then write it out to tape overnight. I don't need partial writes or recovery. There will be no issue writing or reading the whole tape. If I need to recover from tape I have bigger issues than the time required.
