How about some old-fashioned tar-ring to tape? :

Code:

cd /your/mountpoint/..
tar -cvf /dev/<your_tape_drive> ./yourmountpoint

I hope this helps.

I tried this but got hang after some time and it did not completed !
The size of my mount point is 150 GB

what are you understanding from the below !

This is from man tar

1 The ustar header format allows for file sizes to be as large as 8 GB. Therefore, the tar command is enabled to archive files of up to 8 GB in size.

I have no idea. Maybe your tape is simply full? Maybe you used the wrong device (with libraries picking the right one from several pseudo-devices can be quite tricky). Maybe something else.

This is correct.The AIX tar will throw error 0511-825 and quit if you attempt to tar a file with 8GB or more because of limitations in the ustar header format. The same is true, btw., for cpio using the ustar header format ("-Hustar").

You could either use GNU-tar, which doesn't adhere to the POSIX-standard (which is in itself not a problem, it just may pose compatibility problems if you work in a heterogenous environment) but allows files to be up to 50 GB in size or you use some other means to back up your data - TSM, whatever, there are quite a few.

I hope this helps.
