Just a comment on the 2GB error. I create and write to tape tar files
much larger than 2GB, on the order of 20-30GB all the time. I recall
at some point in the past running into the same error you describe when
the output is a disk file. Not sure why tar has that problem on disk
but obviously tar has no way of determining file limits on a pipe. I
typically issue a command like this:
tar -cvf - your_dir | dd of=/dev/st0 ibs=1024k obs=1024k
Then to get it back:
dd if=/dev/st0 ibs=1024k obs=1024k | tar -xvf -
You could probably just specify a disk file for dd and it will work
for that too.
