Thanks Marco What version of tar? 1.14 is known to be busted, 1.13-19 and 1.13-25 are ok, as is 1.15-1. To check, rewind the tape, then use something like: #dd -f=/dev/nst0 |tar -t -(or whatever option tells tar to read the TOC) for a quick listing, or if you have room on /tmp, change the -t to xf or if gziped, 'xzf -'. The final - tells tar to take its input from stdin where the | symbol puts it. Man tar is your friend. -- Cheers, Gene People having trouble with vz bouncing email to me should add the word 'online' between the 'verizon', and the dot which bypasses vz's stupid bounce rules.

I could be wrong, Hendrik, but ISTR there is something wrong with that versions internal checksumming, so there is a possibility they could be, as you said, vapour. It didn't last long on the gnu site, a month maybe before it was replaced by 1.15-1. As to why its *still* in debian, where there is a supposed pride in stability and workability, I have NDI. I've been using 1.15-1 with amandas latest snapshots as they come out for about a year now, my locally built copy is dated Jan 16-2005. It should have been removed from debian, and either 1.13-25, or 1.15-1 inserted in its place. But I'm not running the show, I'm just an old fart that like things to Just Work(TM). -- hendrik -- Cheers, Gene People having trouble with vz bouncing email to me should add the word 'online' between the 'verizon', and the dot which bypasses vz's stupid bounce rules.

Tape's forte isn't its convenience, it's cost and reliability. If you want an easier-to-maintain set of archives, you might investigate a dedicated backup tool such as dump. -- Karsten M.

Second: tar is going to recreate the entire directory tree of these files. My SOP is to create a 'restore' directory someplace convenient, untar into that, and then move the individual files where needed. Regarding the file list, it might be helpful to output the list of files first, then restore them: mkdir restore; cd restore mt rewind; mt fsf 1 tar tvf /dev/nst0 filelist # manually edit the file list mt rewind; mt fsf 1 tar xvf /dev/nst0 $( cat filelist ) mt rwoffl -- Karsten M.
