What if a file stems over onto two tapes. Surely > you'd want the first tape first!! I haven't used ufsrestore in years (about 10 > years > or so) ufsrestore doesn't know how many tapes are in the dump - and neither does ufsdump, for that matter. That's why you have to start with the last tape and work back. ISTR that pkZIP and others worked this way as well, although I haven't used any of those in ages, so I don't know if things are different there or not. -- Ken Real address krgray*at*verizon*dot*net

The way you would do this with a tape that does NOT have an autoloader is: Load volume 1 and specify the files you want and then extract. When it prompts you for the tape number, remove tape one and put in the last tape. Then enter the number of the last tape (3 in your case). If restore does not find the files on that tape, it will request another tape. Remove the last tape and insert the next to last tape. At the prompt enter the number of that tape (2 in your case). If the files are still not found and another tape is asked for, again remove the current tape and put in the previous tape and enter it's number (1 in your case). BUT!! You do not have to do the tpaes in reverse order! You can put them in in any order as long as you enter the correct number to the prompt. Reverse order is only for speed as a tape that is too late in the sequence can be rejected quickly. If you have an autoloader that has it's own idea about which tape to use, you will have to do it the way the autoloader wants to do it. When prompted, enter the number of the tape that the autoloader has loaded. On the other hand, if you can load the tapes manually, do it in what ever order you want. -- Tom Schulz schulz(a)adi.com

Thanks Tom I did eventually get it to work. Pretty much in the same way you described. Thanks for the post though. |
