I was thinking I can do this with a script grapping for the last used tapes in the disklist file. But if someone else know a better solution, please let me know. This is something I've not done. The only way (and I'd bet there is a better way) would be to grab the last 'runtapes' from the list, load the first one of those and scan forward until the tapes labeled date is the date last run. Then run the amverify on each tape in succession starting with that first date match. But I'd think there is a better way. Comment: since the amverify run is a full length pass over the written tape, it is not something I would do as a matter of habit since that will multiply the wear and tear on the changer and the tapes by at least 2, and possibly more times. I'd verify one run a week maybe, just to see developing problems. It does NOT compare the written data with the src data, only verifying that the tape is readable w/o errors. That said, I do it every night, BUT I'm using vtapes on a big hard drive, so the verify pass is essentially free under those conditions. If I was still using (spit) the old dds2 tapes I started with way back when, no way, the wear and tear isn't worth it. amverifyrun is supposed to 'know' which tape was used last based on the log files.

Thats what I meant, ie I can't offer advice as it never uses 2 tapes (for me).

My typical backup runs to about 7Gigs a 200GB drive has room for 21 vtapes, my /var partition and some swap thats only been used once or twice. -- Cheers, Gene There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
