How big can a tar file get?
Because of a big problem I had this weekend, I need to do an emergency backup. I'm basically just creating a tar file of my /home directory. My question: how big can a file get on FreeBSD? This tar.gz file is already 5G. Hard drive space is no problem, but as I'm watching this file grow, I'm wondering if there is some file size limit that is going to make this long backup abort. Naturally, that will happen when the backup is almost complete :-) -- John ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

However traditional tar only supports up to 8GB while the newer ustar format goes up to 64GB. It seems that at least on 7.x tar creates ustar archives by default. -- Bruce Cran ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

I think you're referring to the maximum size of a file tar can store; the total size of a tarfile has no limit, since it's a streaming format. Each stored file is independant of previous or later files, and there is no summary file-list either in the front or at the end. -- Dan Nelson dnel...@allantgroup.com ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
