Re: File-system on tape
No, it isn't. In unix the basic requirement for a filesystem-capable device is
that it be a block-device (as opposed to a character device). The real clincher
is that a filesystem device needs to support random access. Most tape drives
(DDS2 being a notable exception) support only sequential reads and sequential
writes. Not being able to read/write any block on the device independently makes
it fairly impossible to put a filesystem on it.
That said if your real aim is to simply put a whole filesystem on a tape this can
be accomplished with cpio, tar, dump, etc. etc.
