i just had a random idea while reading one of the other threads... maybe fsync is the culprit for the slow initial backups (compared to rsync) ... it would also slow down increments, but assuming a typical rate of file change that wouldn't be as noticable. what would probably be telling is to get some "strace -r -T" output during an initial backup and see just where it's spending its time. i tend to take such output and run it through sort -t\< -k 2,2 ... which would sort on the <n.nnnn> syscall timings... look for the worst culprits then work backwards to figure out wtf rdiff-backup was trying to do when it hit those worst cases... but if you send me some output i can do the data mining. -dean _______________________________________________ rdiff-backup-users mailing list at [email protected] http://lists.nongnu.org/mailman/listinfo/rdiff-backup-users Wiki URL: http://rdiff-backup.solutionsfirst.com.au/index.php/RdiffBackupWiki
