Reg : Backup restore using tar

Mastan — Mon, 08 Nov 2010 16:17:10 GMT

Hi,

We have HP LTO2 Universal Cartridge, inside the cartridge backup1, backup2, backup3 directories are there.

Now I have to restore backup1 directory only, how can I restore using tar command.

Please guide me.

Regards,
Masthan.

Are the /backup* directories stored as '/backup1', './backup1' or 'backup1'? It makes a difference in how you restore.

To find out you could do a:

tar -tvf /dev/rmt/?m

(where the ?m is your appropriate tape device)

If the 'tar -t' show 'backup1' (no leading '/' or './') then you can do:

tar -xvf /dev/rmt/?m backup1

Hi Patrick Wallek,

Thanks for the reply.

Inside the Cartridge we have cold_bkp_01112010, cold_bkp_02112010, arc10, arc11 & arc12 files are there.

Old path for cold_bkp_01112010 (/prod8/backup/ cold_bkp_01112010).

We have taken cold_bkp_01112010 backup and deleted above logical & physical path in hp-ux server and storage.

Now I have to restore cold_bkp_01112010 in different path (/prod4/backup)

Please suggest the same.

Regards,
Mastan.

How do you know what's on the tape? How was
the tape made, "tar" or some other program?
Can you read what's on the tape? How? If it
is a "tar" tape, then actual output from a
"tar tfv" command could be useful.

As usual, showing actual commands with their
actual output can be more helpful than vague
descriptions or interpretations. Often nice
to know, for example:

uname -a

If the file was written with an absolute path, you'll need pax's -s to rename it. (Or gnu tar.)
