In a previous message didn't you say you and 12-13 of these 800Gb databases plus one of about 1.1Tb? I have mine setup so that the next level0 on any one dle still leaves me with 2 older level0's in case the new one is kerflooey. Using a big hard drive, I have 30 days worth of 7/wk backups, so will often have 4 level0's available just in case. Paranoid I guess, guilty. But then the cost of your losing the only level0 is potentially much higher in terms of real money. Get some math together to prove your point that you need more tapes, a lot more, to really have yourself covered. Me, I'd cry & cuss, but life would go on for however much more time I have left, which at 75 & diabetic, is toss coin at any one time.

Gzip doesn't have any warts that I've ever run into. Bzip2, now there is a different bird. I have had it miss complete subdirs in a kernel unpack, only fixable by downloading that versions tarball again. Both were exactly the same size & md5sum. me went off scratching head & never used bz2 again. >I'm rerunning amanda increasing number DLE with total amount of data 3.3Tb.

tape, I would suggest, is not the correct tape, or something. Can you manually unload it, then see if it will reload, using the same syntax shown above? Doing it from the command line might get you a more meaningful error message. My experience with mtx is dated as I went to virtual tapes about 3 years ago, 20x more dependable here, at 10% of the price of a new, still too small changer. If there is another drive available, you should also try to load that one in another drive. >Can you edit and remove my email. thanks I am replying only to the list, as I think it should be. ? -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
