tape usage

[Troyan Krastev]

Hi all admins,

Do you know how to find out home much room is left on a DLT/DDS tape? To backup I use tar command.

Thanks,
Troy

why don't you do the reverse i.e. find out how much data your tape drive will hold , and how much you are backing up i.e. if your tape drive holds 4GB and ypu backup 10 filesystems
and the total data in them are 2GB , you have 2GB left

just a thought

It works for me, but how to count used space?

There no direct way. Try suggestion from this thread (download the utility that Thierry suggested), that works for me.

You'll need a copy of tapeinfo:

There is no partivluar way to find the amount of space left on a Dat other tahn to use it , bcoz the way tar or any other s/w that writes is using blocks , headres etc , approximatation is to see the media size and delte the curretn size of data .

"tapeinfo" is a good tool for finding out how much data is sent to the tape drive and how much data (after compression) is written to the tape.

The only problem is it will not work on some older DDS-2 type drives.

my 2 cents

Thanks to all. I downloaded "tapeinfo" and it works for me.

Thanks again,

Is there a version of tapeinfo available for OpenVMS?
