I backed up a unix database using
"tar -cvf /dev/rmt1 -N 800 /*"
Normally I would restore this using
"tar -xvf /dev/rmt1 -N 800"
This is reporting an error about
"not enough memory"
I have done a new test backup and restore using the same commands and they work.
ANY IDEAS ? (2 Replies)

Note that the all numbers are in 512-byte sectors. --type TYPE Specify the partition type -- dos, bsd, solaris, unixware or gpt. --nr M-N Specify the range of partitions (e.g --nr 2-4). SEE ALSO
