Hello rana,
what is your Architecture, 150 file systems are in a single server?

you can use below command to write data in DAT drive.

rigel:~> tar cvf /dev/nrtape file1 file2 ... dir1 dir2 ...

also check below url for whole listing of command for DAT

better yet, what database?

a straight forward tar done when the db is running won't necessarily be usable for restores, as the db resulting from the restore would be inconsistent.

and how big is the database? will it fit on a dat72? if not, tar probably isn't going to be the answer.

150 Filesystems? that doesn't sound right, but it may be.

one more time:

What OS / version?
What Database?

and do you have any 3rd party backup software installed?

In addition to OldSchool's queries:

Is 150 Gb the maximum size of your file system, or is that the current size of the space being used in that file system?
