Yes by the "modified dump" program I do mean the perl
scripts & the Netapp hack in sendsize.c
I agree that these scripts & the hack will let you
back up certain directories on the Netapp. But the
trouble starts when the directories you are trying to
backup are greater than 20Gb or so.
Is it advantageous to shift to "tar" rather than dumps
while backing up Netapp filesystems ? Or maybe I
should look into AMANDA to see if I can continue to
backup smaller filesystems using "dump" & larger
filesystems on Netapp using "tar"
Any inputs ?
Thanks,
Ashwin.
