For as I understand there should not be a limit on the Tar command - it is designed to do large files.
I prefered to do a UFS dump to tape though on large files
Here is the tape backup script I use after mounting the tape
for i in `cat /backup/fslist`
do
ufsdump 0cuf servername:/dev/rmt/0n $i
done
echo "****************"
echo " BACKUP COMPLETED "
echo "****************"
The /bakcup/fslist file contains all the directories I wanna backup. And servername = your servername
I understand your pain, I got 8 Oracle databases on each of my servers, I wanna kill my DBA....

tcopy(1) User Commands tcopy(1)
NAME
tcopy - copy a magnetic tape
SYNOPSIS
tcopy source [destination]
DESCRIPTION
The tcopy utility copies the magnetic tape mounted on the tape drive specified by the source argument. The only assumption made about the
contents of a tape is that there are two tape marks at the end.
When only a source drive is specified, tcopy scans the tape, and displays information about the sizes of records and tape files. If a des-
tination is specified, tcopy makes a copies the source tape onto the destination tape, with blocking preserved. As it copies, tcopy pro-
duces the same output as it does when only scanning a tape.
The tcopy utility requires the use of Berkeley-compatible device names. For example,
example% tcopy /dev/rmt/1b /dev/rmt/2b
