Append in fbackup

mehul_3 — Tue, 17 May 2005 02:55:44 GMT

Hi there!
I wanted my backup with appending the contents to previous one say fbackup -v -f /dev/rmt/0m -i /u01/gdbs
I tried to get help from man fbackup but I could not find any switch to appending the contents.

hi,

i do not think u can append content to the tape after a fbackup session has completed. read this thread:

use tar or cpio if you want to do so.

btw, u should really assign points to the others cause if u really want help, show that u appreciate the assistance given as well.

You can't do that.

fbackup will **ALWAYS** rewind the tape before it starts the backup. No appending is allowed.

If you are talking about fbackup, then NOTHING.

You CAN NOT append to the end of a previous backup with fbackup. It is not supported.

If you are using other means to backup, you can try using one of the no-rewind tape device files. Those are the files that the 'n' in the name. Like /dev/rmt/0mn, /dev/rmt/1mn, etc.

I have a following entry in /etc/fstab file
/dev/vg03/lvol1 /u01 vxfs delaylog 0 2
/dev/vg03/lvol2 /u02 vxfs delaylog 0 2
/dev/vg03/lvol3 /u03 vxfs delaylog 0 2
/dev/vg03/lvol4 /u04 vxfs delaylog 0 2
/dev/vg03/lvol5 /u05 vxfs delaylog 0 2

From above, can I use tar command to copy more than 2GB and appending contents to previous backup.

Pl, correct me if I am wrong

With warm regards

Yes, that WILL work with tar. tar allows you to use the no-rewind devices and keep appending data to the end of the tape.

You can also do that with cpio.

Just remember that you can NOT do that with fbackup because fbackup rewinds the tape completely before each backup no matter what tape device you use.
