[Dump-users] Value of recording number of blocks in tape archive?

[Abner G. <67...@gm...>]

I am a relatively new user of dump. Previously I had been using tar to back
up data to tape. I keep a small database where I manually record some basic
info about each backup such as a brief description of the content of the
archive, file number on tape, tape number, size in MB, and  transfer rate.
I also note the backup in my paper planner just in case.

I am wondering if there would be significant value in recording the number
of blocks written to tape as reported by dump? I could see this possibly
being of value in the case of a corrupt tape, maybe? Maybe of use to verify
the integrity of the archive?

Has anyone found this information useful in any regard?
