OpenRsync is OpenBSD's rewrite of rsync. openrsync is designed to be lightweight and simple. It may, however, be a little buggy.
WARNING: If your filesystem is being actively written to, data corruption may occur.
To back up the file /path/to/file on example.com with username to the current directory:
$ openrsync -a firstname.lastname@example.org:/path/to/file ./
This table explains the most common options:
|a||(a)rchive mode, shorthand for Dgloprt|
|D||Transfers (D)evice and special files|
|g||Sets (g)roup to match the source|
|l||Transfers symbolic (l)inks|
|o||Sets (o)wner to match the source (needs root)|
If you have multiple files, you can use the shorthand of :/path/to/second/file:
$ openrsync -a email@example.com:/path/to/file :/path/to/second/file ./
This copies both /path/to/file and /path/to/second/file from example.com to your current local directory.
openrsync can also copy folders recursively. To see each file copied, turn on verbosity with
-v. In the next example, we copy from /path/to/folder on the local system to /path/to/destination in
$ openrsync -av /path/to/folder firstname.lastname@example.org:/path/to/destination/
Before you backup your files, make sure you have enough disk space. To see how much space it will take, and how much you have available, run:
$ df -h Filesystem Size Used Avail Capacity Mounted on /dev/sd0a 1005M 111M 844M 12% / /dev/sd0k 192G 28.7G 153G 16% /home /dev/sd0d 3.9G 22.1M 3.7G 1% /tmp /dev/sd0f 12.3G 7.3G 4.4G 63% /usr /dev/sd0e 14.7G 41.2M 14.0G 0% /var
Backing up /home will require at least 28.7G of space.
$ openrsync -av email@example.com:/home/username /dest/path/
This will copy everything in /home/username on
example.com into /dest/path/.
