make tar archives muti volume...?

[jackfiled]

Hi all
I want to make tar archive file.
Created tar file limited specified size

for example
In sub dir size is 3072MB, tar created files are 1535MB each

How can execute that command?

In the gnu tar man page there is an -M qualifier this creates a multi volum tape !

I have never tryed such a long tar file myself but always have belief this did the trick ?

Have you tryed this ?

Hi,

just curious. Is it because of limitted space on disk, that you want to split it? If not make the tar file one file and then split it using split or so.

greetings,

Michael

Hi,maybe You can give split-tar a try. It can create standalone tar's at the given size.You can find it under http://www.informatik-vollmer.de/software/split-tarThomasPS: I'm not related to Jürgen Vollmer in any kind ;

hi,

more complex, but does work:


mknod /tmp/mypipe p
split -b1M - /dir/mytar < /tmp/mypipe &
tar cvf /tmp/mypipe /dir/files
rm /tmp/mypipe

to restore:
cat /dir/mytar* | tar xvf -

adjust the size parameter in the split commands to your needs (set at 1MB in this example).

regards,
Thierry.

Jackfiled,

Huc is talking about GNU tar. This tar doesn't come with HPUX. You will need to install it first. You can then use the "-M" option.

You can get GNU tar here.

Actually Huc, I think I got it wrong :)

This is in the linux forum but my head was in the HP-UX forum!
