Backup with tar

I am planning to backup my Solaris Servers to SAN storage using tar.
Also palnning to automate the job using Crontab.
Can anyone advise how to make the date change automatically everyday for backup.

Pls correct me if I am wrong. Thanks

You want the cron job to update itself daily? Why not just make one cron job that works for all days?

Why not use pax?

Hi Corona688,

Thanks for ur reply.
Yes , i have to make one cron job for all the days.
But I want the backup file on SAN to be renamed automatically to that particular date.
e;g feb 1st file will be like feb0109.tar
2nd Feb file like feb0209.tar
Can we do that...??? Or any other better suggestion?

Look at the man pages.. (too much options to just try to brief...).
Most important: it can read tar and cpio files, can backup devices files knows how to deal with links, backup only modified files since last backup etc...
Check on how you version manages files of 2GB or greater ( can have limitations...)

I think this should work in a cron job, someone correct me if I'm wrong:
Code:
tar -cpf "$(date +%b%d%Y).tar" /path/to/files

It will make files like Feb022009.tar, see 'man date' for date's syntax if you want to change it around. Personally I prefer YYYYMMDD since it sorts so nicely.
