Does rsync remove deleted files?
before means all the files are deleted, and THEN rsync copies over the files. during means as it goes through the list of files, it deletes them when it comes to them, and after means it waits until all the files are transferred over and then deletes the remote side.
Is rsync good for backups?
The rsync command-line tool is the most preferred backup tool in Linux systems for multiple reasons. It allows you to make incremental backups including the entire directory tree, both locally and on a remote server. Better yet, you can automate the backups using shell scripts and cron jobs.
Is rsync destructive?
rsync will work in a non-destructive way by default, like our overwrite but not delete strategy. So new files will be written and replaced, but old files will not get deleted.

Does rsync overwrite data?
rsync will always overwrite files at the destination unless you tell it not to do this (option -u, –update ).
Is cp or rsync faster?
rsync is much faster than cp for this, because it will check file sizes and timestamps to see which ones need to be updated, and you can add more refinements. You can even make it do a checksum instead of the default ‘quick check’, although this will take longer.

How to make backup from source without deletion?
So if any file or folder added in source, it’ll be synced to target without any deletion. I suggest you to use rsync for make backup from source files and use find rm for deletion files for period of time or size of files:
Does the rsync cron task delete older backups from Dropbox?
The backup plugin eventually did its job and deleted the older backups, so I was expecting the rsync cron task to subsequently delete the older backups from my Dropbox folder to match the source folder, but it has not done so. So I have a couple of questions:
