 ## Introduction
 
-Using `rsync` over SSH is not as powerful as [lsyncd](../backup/mirroring_lsyncd.md) (which allows you to watch a directory or file for changes and keep it synchronized in real time), nor as flexible as [rsnapshot](../backup/rsnapshot_backup.md) (which offers the ability to backup multiple targets from a single computer). However, it provides the ability to keep two computers up to date on a schedule that you define.

 If you need to keep a set of directories on the target computer up to date, and you do not care about real-time synchronization as a feature, then `rsync` over SSH is probably the best solution.

 ### Preparing the environment
 
 This example will use `rsync` on the target computer to pull from the source instead of pushing from the source to the target. You need to set up an [SSH key pair](../security/ssh_public_private_keys.md) for this. After creating the SSH key pair, verify passwordless access from the target computer to the source computer.
 
 ### `rsync` parameters and setting up a script
 
-Before script set up continues, you need to decide what parameters you want to use with `rsync`. Many possibilities exist. Review the [manual for rsync](https://linux.die.net/man/1/rsync) for a complete list. The most common way to use `rsync` is to use the `-a` option, because `-a`, or "archive", combines several common options into one. What does `-a` include?
