Dump and Tar File Sizes?

[SLG]

I'm using a combination of dump and tar (dump for filesystems and tar for directories) to backup my Linux systems. Some of my dump and tar files are very large (+100gb) and I'm wondering what is the limit of tar and dump files? I don't have the space to do a test restore without wiping out the production filesystem and restoring to it.
Thanks in advance!

I've googled tar file sizes and I see conflicting information. I've found some posts say less than 2gb, others say 8gb max, while others say unlimited. I can't find anything on dump file sizes.

The tar format is just a sequential concatenation of files and as such has no 'limit' per se. The only thing limiting the size of a tar archive would be the file system it is created on. I've done backups of my file server with more than 200GB onto DLTs & some 50GB to 100GB of temporary backups on a PC with ext3.
