Hi Zoltan,
I agree with you in regards to making a backup of file systems that contain System files like /, /usr, /var, etc. However, I don't think it is the backing them up that is a problem. It is how do you restore them? If you need to restore an image of /, /usr or other System related file system then you almost certainly will have to restore the entire OS any way. So I am not quite sure how effective an image backup of these file systems would be. You will need an OS with a TSM B/A Client installed in order to restore the image. You might be able to get this to work in AIX or Linux (not familiar enough with HP-UX or Solaris) using a dual boot system and boot one OS while you restore the other, but it will be tricky making the new target disk or partition bootable. In Linux using GRUB you should be able to get it done without too much trouble. In AIX, I am not sure how you would get the bosboot command to set the boot sector of the disk where the restored file systems were.
This is an interesting problem, but there is already an alternative why to solve this problem using BMR or Sysback, so why reinvent the wheel.

You can use the IMAGETYPE=dynamic option !
From the 5.2.x book:
dynamic Replaces the dependency on the copy serialization value in the management class to perform an image backup without unmounting and remounting the file system read-only. Use this option only if the volume cannot be unmounted and remounted read-only. Tivoli Storage Manager backs up the volume as is without remounting it read-only. Corruption of the backup may occur if applications write to the volume while the backup is in progress. In this case, run fsck after a restore. This option is valid for AIX, Solaris, HP-UX, Linux86, Linux IA64, Linux pSeries, and Linux iSeries.

You can only take image backups of Linux filesystems if you can unmount the filesystem. This requirement will prevent you from image backups of filesystems containing system files, such as /, /var, /etc/, and /usr.

Dear All, Please share your experience on taking open file backup and image backup on Linux (including system files).
I have been going through documentation and manuals, but there are so many IFs and BUTs involved.
My scenario is to take cold backup of Oracle 9i on Linux, which is fine, but with this I need to take entire system backup so that I can restore my server real soon in case of disaster.
Please share practical implementations that you gurus are using !!!
Thanking you! This list has been a source of real good knowledge to me !
Kind Regards Sandra
