Excellent point. Which leads to a request - good references on a well behaved compressed FUSE FS that - supports RW - behaves well with rsync (which I presume mmaps files liberally) - supports hardlinks and ACLs As a happy user of large hard drives, I haven't needed a compressed FS since the unhappy days of DRDOS so I'm rusty on this front. There's a listing at http://fuse.sourceforge.net/wiki/index.php/CompressedFileSystems but I know nothing about the quality, reliability and performance. I care mainly about the reliability -- but it better be fast too. Compression ratio is perhaps more negotiable, the other two arent :-) A good FS would give us huge benefits on the backup front: - Right now, the jffs2 fs can outstore the backup storage on highly compressible content. Not a good look, and leading to all sorts of bad scenarios. - More storage means the backup quota for each user can hold more "old" files. - Reasonably good compression means that we can squeeze HD space a bit, for example in really large schools. > For more background, see this thread: > http://lists.laptop.org/pipermail/server-devel/2008-September/002058.html > > Also, this feature is on by default when using XO 8.2 and XS 0.4. > There's no GUI to turn it off but I assume you could disable it on the > XS with a few manual changes to the config. There's a config file (/etc/httpd/conf.d/ds-backup.conf I think) - remove it and ds-backup is no more. cheers, martin -- [EMAIL PROTECTED] [EMAIL PROTECTED] -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
