This may seem like a moronic question, as I have done this countless times before, and now I can't quite seem to get it to work. I am running FreeBSD 2.1.5-RELEASE and have just bought a shiny new Exabyte 8505XLI tape drive. I am attempting to back up several filesystems as different tape files. e.g. cd /somewhere ; tar cf /dev/nrst0 * cd /somewhere/else ; tar cf /dev/nrst0 * I have done this before with other UNIXes. Now I am attempting to restore these directories (actually just verify that this is happening) with: mt rewind tar tf /dev/nrst0 > filelist.1 tar tf /dev/nrst0 > filelist.2 the first one always works (and is the one I backed up first) the second one never does. I have tried writing filemarks using mt between the two backup procedures. It seems to never find the second archive. It is my understanding that the tar will write the file to tape and write an EOF mark, then the second file, and another EOF mark. Upon restore, after the first file is restored the tape should be in position to read the next tarfile. It doesn't happen. I have also tried rewinding the tape and using the mt command to skip to the next filemark and reading the next archive, but it doesn't work either. Does anybody know what is going on? Please email any replies as I am not on the mailing list.
