It still explodes in size. I can't necessarily use raid or dd because the drive sizes are different. my external drive is much smaller than my actual backup drive. At my backups current space usage, I can fit it on the external drive but I don't want to limit my actual backup drive to my externals size. That's why I am trying to get rsync to work the way that I want it to.

How do I keep the sizes the > same? cpool uses hardlinks. rsync by default does not preserve hardlinks which is why the copy you make explodes in size. If you specify -H to rsync, it will preserve hard-links, but expect it to take a LONG time. More common backup methods is to use a RAID1 array for the backup pool, when you want to make a backup, insert a drive and let the RAID sync up the backup drive. Another method is to backup the raw partition image. -Dave ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
