Perhaps you filled the first tape.


I see no description of the system where you
did this. Output from "uname -a" would be a
nice start.

This does not seem to me to be a very
complete explanation of what you did.

Does this tape drive have different density
and/or compression options? Which ones did
you specify?

Did you start with a blank tape?

Re: fbackup through sam

See this post:

and refer to Bill Hassell's remarks regarding a config file (or the lack thereof). You need to be able to keep the drive streaming and write fewer / bigger blocks.

Also, see my remarks about the impending demise of fbackup (it's being obsoleted).

Fbackup always rewinds the tape and starts at the begining, so you *should* be getting more that ~260MB on it. If you've got lots of bad spots, or lots of record gaps, that will reduce capacity.

What happens if you clean the drive and use a new (or known good) tape.

Re: fbackup through sam

Also make sure you are using an LTO3 TAPE in the LTO3 tape drive.

If you happen to be using an LTO2 (200 GB) or LTO1 (100 GB) tape, then that would explain your problem as well.
