tar restore from tape

renarios — Sun, 09 Jul 2006 13:49:37 GMT

Hi all,

I currently installed fedora core 5 on my machine and I have to restore some files from my dds3 tape. If I issue the command tar -xvf /dev/nst0 -f $file I receive an error.
Can anyone tell me what the default blocksize for tar is on fc4 and if that is different from fc5?

tia,

Renarios

There shouldn't be one.

Things to do:

First, what was the error you received? You didn't say.

Also the tar command you've given has two -f's. Why?

Can you list the tape with a flat tar:

tar tvf /dev/nst0
(NOTE: No, you don't need the -, and you can stack the command arguments).

Can you read data from the tape using 'dd' after doing an 'mt -f /dev/nst0 rewind' ?

What make/model of drive and how is it connected? You've said 'DDS3', so it's probably a SCSI drive, contents of '/proc/scsi/scsi' ?

Hi Renarios,

the correct syntax for tar is as follow:

tar xvf /dev/nst0 $file

You should check if the $file is/are in archive by using:

tar tvf /dev/nst0 $file
