Backup with a date stamp in Filename on Hard Disk.

[salimwng]

OS Platform: SCO Unix Sys/V

Hello,

Beside of doing backup on tape everyday, i would like to do the backup on Hard Disk too. I have created a batch file for doing this but however i DO NOT WANT it to be overwritten everyday. The command is

tar cvf /ibm3/bakXXXXX.tar /u/peg

/u/peg --> is the Data folder which need to be backed up.
/ibm3/bakXXXXX.tar ---> is the filename i want to put at it.

The problem is that i would like to know if there's a command which exist or a short program which can automatically assign the filename ( in the place of bakXXXXX.tar ) as per the date stamp. That is if today is 01.07.2002, the filename is bak010702.tar and tomorrow will be bak020702.tar and so on and so forth.

Could anybody help me please, i have been trying lot's of stuff but in vain.

Thank you so much
Regards.
Salim

Easy one - and many ways!

To get the date in the format you want use

date -u +%d%m%y
# This will give date as 070102

If you set a variable for date and then call it from the backup routine your using you should be OK.
i.e.
todaysdate=`date -u +%d%m%y`
tar cvf /ibm3/bak$todaysdate.tar /u/peg

Not too sure if it will like the bak before the variable. Try it!

We backup some critical file directories to the hard drive on a daily basis. In our case we backup only for a week. We back up the entire system daily on tape. The daily backups are for quick reference. In our case:

DATE=`/bin/date +%A`

cd /u/appl/filepro
tar cvf /tmp/u_${DATE}.tar ./*

This is only the first few lines, but you can get the idea. 'man date' to get the variable setup that works best for you.
