RE: [cobalt-users] Cobalt RaQ3 Backup

["DIGS Ltd - Denis Tanguay, P.Eng." <denis@xxxxxxx>]

Hello Simon,

Do a man tar at your telnet prompt and you will get all the details on the
option settings for tar.

I am completing a perl script that you can put into cron for daily backup.
Should be completed today.

The beta version is working great. Just doing some minor change to create
multi session and mutil volume.

The tar options -cvfzp are as follows:

c: create a file
v: verbose, i.e. all file tarred will be echo back at the prompt assuming
you are doing doing from telnet/ssh
p: preserve the permission setting of the files
z: gun zip the tar file

you may also want to add "r" for recursive, i.e. all the sub-directory below
the directory you mentioned.

Have fun.

Hi everyone,

Thanks for all the help. Whilst I understand what you're saying, not being
technical I don't know how to put it into practice.

Is it possible someone could explain what the 'p' switch and -cvpf are, or
possibly edit the instructions below to implement them?

I'm so sorry if I sound really thick, but Linux isn't my strong point! Any
help would be very graciously appreciated!

We've tried the above method and it has worked nicely although don't forget
about /home .

The command tar -cvpf will be better suited in order to keep the file
permissions and ownership in tact.
