Well, I just saw a proposal on linux-kernel which addresses inode allocation performance issues on ext3/4 by preallocating contiguous blocks of inodes for directories. I suspect this would help reduce the number of seeks required when performing backups. If there is another filesystem which does this I imagine it would perform better than ext3. > Do you know any alternatives to backuppc with web gui? which probably > works faster? :P BackupPC is the best. Most backups complete in a reasonable time, those that don't are backups which are either very large (lots of bandwidth) or have lots of files. My backup server is a simple Athlon XP 2000+ with a RAID1 consisting of 2 Seagate 250GB 7200rpm ATA drives. More spindles and/or disks with faster seek times is the way to go. -Dave ------------------------------------------------------------------------- Take Surveys. Earn Cash.
