Below are examples of rsync commands and their async equivalents for uni-directional synchronization.
Options:
rsync command:
# rsync --stats -v -r -u -l -t -o -g -p /media/ editor@docserver:/backups/media
async equivalent:
# async -N Oneway -u -t -j -d /media/ -r editor@docserver:/backups/media -l 100M -w d0c5 -K push -c none
Options:
rsync command:
# rsync --stats -v -r -u -l -t -o -g -p /media/ --include="/media" --include="/media/wmv" --exclude="/media/.*" editor@docserver:/backups/media
async equivalent:
# async -N Oneway -u -t -j -d /media/ --include="/media" --include="/media/wmv" --exclude="/media/.*" -r editor@docserver:/backups/media -w d0c5 -K push -c none
rsync Option | async Option | Description |
---|---|---|
--stats | Enabled by default | Display file transfer status |
-v, --verbose | Enabled by default | Increase verbosity |
-q, --quiet | -q, --quiet | Disable progress display |
-r, --recursive | Enabled by default | Recurse into directories |
-u, --update | If a file exists at the destination with the same name, then async's default behavior is to do nothing if the files are the same (size and checksum), and overwrite if the file is different. | Skip files that are newer on the receiver |
-l, --links | Linux and Mac OS X: -n copy,
--symbolic-links=copy Symlinks are skipped in Windows. |
Copy symlinks as symlinks (Linux and Mac OS X only) |
-t, --times | -t, --preserve-time (must have Enterprise Server, Connect Server, or Point-to-Point 3.1+) | Preserve modification times |
-o, --owner | -u, --preserve-uid | Preserve owner |
-g, --group | -j, --preserve-gid | Preserve group |
-p, --perms | With regard to directory attributes, if the source mode doesn't have sufficient owner permissions, then the destination will add: owner rwx. | Preserve permissions |
--version | -A, --version | Print version number |
-h, --help | -h, --help | Show help |
--include-from=file | -I, --include-from=file | Include filter (text file with paths for inclusion). See Include/Exclude Filtering Rules. |
--exclude-from=file | -E, --exclude-from=file | Exclude filter (text file with paths for exclusions). See Include/Exclude Filtering Rules. |
--include=pattern | --include=pattern | Include paths that match pattern. See Include/Exclude Filtering Rules. |
--exclude=pattern | --exclude=pattern | Skip paths that match pattern. See Include/Exclude Filtering Rules. |
-c none | rsync, as a protocol, does not encrypt on its own; however, rsync can enable/disable the SSH encryption protocol (using option -e ssh). |
