rsync -rva --exclude="gemeinsame Dokumente/Videorecorder" --delete-excluded --delete-after "/home/" "stefan@192.168.0.30:Backup/" Parameter (auszug aus der manpage): -c, --checksum This changes the way rsync checks if the files have been changed and are in need of a transfer. Without this option, rsync uses a "quick check" that (by default) checks if each file's size and time of last modification match between the sender and receiver. This option changes this to compare a 128-bit MD4 checksum for each file that has a matching size. Generating the checksums means that both sides will expend a lot of disk I/O reading all the data in the files in the transfer (and this is prior to any reading that will be done to transfer changed files), so this can slow things down significantly. The sending side generates its checksums while it is doing the file-system scan that builds the list of the available files. The receiver generates its checksums when ...
