The -z option for rsync will compress for the transfer, but the file will be decompressed before it is written to the disk (having the same file at both ends being the point of rsync..) If the files change a lot and you need to do a lot of incremental backups, I'd use rsync and just give up the space to store the uncompressed files if you can. Otherwise, if the files are generally small or rarely change, you could pipe the output of dump over ssh and through gzip and into an archive, and then do incremental dumps the same way. Can be automated nicely if you set up an authorized keypair so you don't need to enter a password. Note that I've removed the hackers list from the recipients. This is totally off-topic for that list. Marcus > > Thanks, > Simon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
