1 | This patches creates two new command line options as follows: |
2 | --delete-dir | |
3 | --delete-suffix | |
4 | ||
5 | The delete-dir and delete-suffix options give the ability to store | |
6 | backup of deleted files on the receiver in different directories | |
7 | or with different suffix than the backup of files that have been | |
8 | changed but that are still on the source drive. Both commands can | |
9 | be combined. | |
10 | ||
11 | The default behaviour if one or both of the options are not specified | |
12 | is the previous behaviour, both backups use the same directory or | |
13 | suffix. | |
