tar size limit
i'm trying to use tar to backup a number of directories. i tried tarring a couple that are some 7+ gb, and tar died w/ the error:
"size limit exceeded" or something similar. the resulting size both times was approx 2gb. can tar not handle creating archives > 2gb?
the man pages said nothing of a size limit!
The limitation isn't inherent to the kernel or the GNU tar program, but is a problem of the filesystem. Ext2 only supports file sizes up to 2Gb (gotta remember how old ext2 is, 5 years? something like that). I don't know if ext3 beats the 2gb limit, but I'm pretty certain Reiser is alright, and I know XFS and JFS don't have that problem.
I have a question about limiting the size of tarball archives. I'm developing a backup system that pulls data off remote boxen and tars and compresses them (tar -zcvf...). I want the option of burning these archives to a cdrom, so they should be limited to about 650 megs a pop. I am pretty sure i've read that tar can tell when it's reached a size limit, close off the archive, and start a new one; but for the life of me I can't find the article!! Can anybody shed some light on the subject?
