I am trying to do a restore on a backup tape (DDS2) and am having a little trouble. For one, I dont know how the tape was made, whether is was tar, cpio, dump..etc. Anyone know how to restore a tape without knowing the format of the backup?
also, im running on hp-ux B.11.00
You cannot extract/restore data from a file/tape unless you know the format in which the backup was taken. Try using various utilities one by one to restore the tape.
not sure if this will work but...
-------------------------------------
IDEA:
You can use the fstyp command to find out what filesystem a device is.
Example:
# fstyp /dev/rdsk/<tape device>
ufs
You could also use a shell script like so to determine all devices in the /dev/rdsk directory:
for i in /dev/rdsk/*; do echo �$i = $(fstyp $i 2>/dev/null)�; done
-------------------------------------
Hope this helps!
why don't you try find out with the command file what type of file ( tar cpio gzipped ) this is ??
did the OP get anywhere with this info? i am having similar problems
