Randy,
Thank you very much for being with me in my tape drive problem.
Currently I am running a backup of file system which is almost 30gb with tar
command. The command syntax I have used to start the backup is:
# tar -cvMf /dev/tape .
where 'M' is to support multiple archives. I am wondering now that almost 15
gb (while the total capacity of the cartridge is 8gb in comressed mode, 4gb
in normal) data is backuped up and it neither stopped nor asked for another
tape cartridge. I dont why is this behaviour going on. Perhaps, it is
finishing the tape and assuming the same tape as the next available
cartridge and that's why it is not stopping.
Do u think this is a normal behaviour. To me, it does not seem logical.
Please comment.
Naeem
