Backing up your files with rsync
rsync makes the task a lot easier as it only downloads files that have changed - saving time and bandwidth.
Setup ssh keys so that you don’t need to enter a password each time you attempt to rsync folders.
On the destination server, the command is as follows:
-e ’ssh -p 2222′: this ensures rsync uses the SSH protocol and sets the port.
-avl: This contains three options;
(a) is archive mode which basically keep the permission settings for the files.
(v) is verbose mode. You can leave it out or increase it by appending two v’s (-vv).
(l) preserves any links you may have created.
–delete: deletes files from the destination folder that are no longer required (i.e. they have been deleted from the folder being backed up).
–stats: Adds a little more output regarding the file transfer status.
–progress: shows the progress of each file transfer. Can be useful to know if you have large files being backup up.
