[Info-vax] backups and compaction or nocompaction might be better

[pcoviello at gmail.com]

details vms 8.3-1h1  lto4 tapes 8 tape autoloader with encryption. San clones/copies for backup source. so the tapes raw capacity is 800gb and below is a chart of what approximately goes to each tape per night, it does vary. something else that may make a difference is that the databases that reside on the disks are cache which is fine but they too are encrypted. I can use as few as 3 tapes and as many as 5.

my backup command
backup/noassist/norecord/noinit/ignore=(inter,label)/fast/media_format=compaction/group=0/image/block=65024


so basically should I be able to use compaction?

thanks 
Paul
