They don't change a whole lot, but they do change and new ones are uploaded. What I'm trying to do is build massive network backup server, backing up 6+ servers simultaneously. Each server has about 50-100gb worth of data to be backed up daily. I did look at dump, looks great, the only problem is that it can't backup individual directories, rather whole filesystems, if I didn't misread something. -Simon On Fri, 13 Dec 2002 06:27:29 -0800, Marcus Reid wrote: >On Fri, Dec 13, 2002 at 03:22:06AM -0500, Simon wrote: >> >> rsync is nice, but it can't (afaik) compress data being synced on the fly to >> save disk space :-( Is there anything out there which works like rsync and >> can compress on the fly to space disk space? having 100GB of text files >> compressed can save quite a few gigs. > >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.
