Is rsync good for backups?

Rsync is a Linux tool used for backup and file recovery. It transfers and synchronizes files between a machine and an external hard drive, or across a network. Rsync makes the process more efficient by comparing the modification dates and sizes of files, and only backing up when needed.

Does rsync copy or move?

You can pass --remove-source-files to rsync to move files instead of copying them. But in your case, there's no point in using rsync, since the destination is empty. A plain mv will do the job as fast as possible.

Rsync with --ignore-existing-files: We can also skip the already existing files on the destination. This can generally be used when we are performing backups using the –link-dest option, while continuing a backup run that got interrupted. So any files that do not exist on the destination will be copied over.

How do I rsync between two servers?

How do I get rsync?

Why does rsync take so long?

This is because the delta algorithm is assumed to only be faster than a whole file transfer when transferring over a network. When using the delta algorithm, the whole file would need to be read and checksummed on both the source and target systems.
