cpio backup

[rajeshbahl]

We need to take cpio backup on our sco openserver 5.0.5 having tape drive to take the backup of another server running the same OS.

Can somebody suggest the procedure / syntax for the same ?


Thanks In Advance

find /filesystem -depth | cpio -ocvB -O /dev/rmt/0c does the trick for me. Annihilannic.

Sorry, put your tape device in the place of /dev/rmt/0c (I was in Solaris mode), probably /dev/rct0. Annihilannic.

find /filesystem -depth | cpio -ocvB -C 10240 -O /dev/rct0

and restore with

cpio -idvuk -I /dev/rct0 -C 10240

and read cpio -itv -I /dev/rct0

or you can take a level backup

find / -mtime -1 |cpio ..... =-=-=-=-=-=-=-=-=-=-=-=

BUT THIS WILL TAKE THE BACKUP OF LOCAL SERVER ONLY. WHAT ABOUT THE REMOTE SERVER ?

Ah, missed the "another server" in the question.

Try setting up rsh permissions from the source server to the destination server, then use something like:

[tt]find /filesystem -depth -mount | cpio -ocvC32768 | rsh tapeserver "dd of=/dev/rct0 conv=bmode bs=32k"[/tt]

I have had problems with backups like this before though, so double-check that you can actually restore from the tape before you start to rely on it as a backup method. Annihilannic.

Using the -O switch as described on the man page, copied below, you should be able to, but only on a local tape drive.

[tt] -O file[, file ... ]
Direct the output of cpio to file. If file is a character-special
device, when the first medium is full, replace the medium and type
a carriage return to continue to the next medium. You can change
on directories that are being copied.[/tt]

Yes, it would back up everything except low level things like your partition tables, boot blocks, etc. Also it would put all of your mounted filesystems into one large archive, so in a recovery situation you might have to restore them selectively. Annihilannic.
