EOF message on tape drive

Hi there

I have problem on archiving some Oracle files.

Total folder is little over 25G, and when I try to archive this folder onto a tape (40G capacity), after about 2/3 of files, I get EOF message.

I have typed next command:

cd /index/Backup

tar cvf /dev/rmt/0 .

and messages about archiving in verbose mode start, and after few hours (and about 65 of 94 files) I get the message:

tar: write error: unexpected EOF

Since I saw in some previous message that I can not see what is total amount of files on tape, and what is free space on tape, how can I solve this problem and do the backup in total?

Thanks

P.S. System is Solaris 8 on 280R server.
