Hello, I'm new to rsync, and I'm confused about something. I was under the impression that it used some sort of diff function to save time & bandwidth when copying over files. I'm using it to backup files from one computer to another, and it works exactly as I thought it would, except that it seems to be copying entire files over when they've change rather than the differences. This is a problem with a few huge mail spools that I need to back up; even if there's just a couple messages appended to the end, it copies over the entire file. Here's the command I'm running:
rsync -vvaRbS --backup-dir=/backups/rsync/old --delete --rsh=ssh \ --exclude="*.core" --numeric-ids --stats --progress --bwlimit=100 \ /usr/local /home /var/mail remotehost:/backups/rsync/current Am I missing something here? Does one of these options imply "-W"? Possibly relevant: I'm running rsync 2.5.2 client-side but 2.5.3pre1 server-side. 2.5.2 kept coredumping on the server for some reason. I would have investigated further had 2.5.3pre1 not fixed it. Both boxes are FreeBSD 4.5. ------------------------------------------------------------------------------- Kim Scarborough http://www.unknown.nu/kim/ ------------------------------------------------------------------------------- "I have to applaud whoever thought of making a big hot dog shaped car, and then made that vision a reality" - Chris Scales ------------------------------------------------------------------------------- -- To unsubscribe or change options: http://lists.samba.org/mailman/listinfo/rsync Before posting, read: http://www.tuxedo.org/~esr/faqs/smart-questions.html
