How big was the dead disk? Do you have space to store the whole thing? Did amanda do a level 0 of the whole dead disk to 17? If not, there are very likely pieces of that disk on several of your virtual tapes. amrestore deals with all that. > The backup in question is on (virtual) tape number 17.

What I'd do is recover the last files amanda backed up from that disk, using amrestore. I'd restore to a disk, consider that the perpetual backup, and not try to get that old disk data anywhere in amanmda's database -- amanda is very much oriented to reusing things in a cycle, and trying to get her to change her ways can be difficult. amrestore's a pleasant piece of software to use. You just tell it the date you want to restore, the disk, the files, and some other things (I use it infrequently, and I have to read the man page every time). amrestore figures out which tapes you need, and restores the data. Then you can do what you want with them -- burn to optical, buy a new disk, whatever. -- Glenn English
