Meanwhile I have found a big error of myself ... My 2nd Partition which holds the source for the backup wasn't fully alligned to the 4KiB-Blocks of my "Western Digital HDD". (I don't know if you are familiar with this kind of harddisks: In short they have clustersizes of 4096 Bytes (instead 512), because most operating system work with 512 Bytes, the harddisk itself pretends to have 8x512 clusters instead of one 4096. If you don't allign the harddisk to this sizes (if you start at sektor 63 instead of 64 (or any dividable through 8)) it has performance issues.) I thought it was alligned, but I made a mistake by one sektor, so I got a problem. The second run was always faster (perhaps some caching). Now I have alligned the 2nd partition correctly. > > As a first step I would suggest posting this question to the rsync mailing list.

Performance right now using any of the 3 programs: Around: 23GB Files: 145.056 Directories: 51.882 Time: 11-12 minutes I assume this is a "not so bad" value, but perhaps I get some more input regarding speed from rsync. > > Thank you. > > > > > > _______________________________________________ > lbackup-discussion mailing list > http://www.lbackup.org > > Change options or unsubscribe : > http://lbackup.org/mailing_lists _______________________________________________ lbackup-discussion mailing list http://www.lbackup.org Change options or unsubscribe : http://lbackup.org/mailing_lists
