Rsync Tool Features:

1. Host-local data transfer, similar to the CP/RM command.

rsync Removal Method:

Create a new empty directory with Rsync-r--delete/empty directory/Destination directory

Note that after the directory name to add/

2. with ssh/ The RCP channel transmits data similar to the SCP command.

Example : push file

3. Transfer data in daemon mode. (in fact, to avoid remote host transfers using SSH Channels)

Server configuration file/etc/rsyncd.conf ( manual creation required)

UID = rsync

GID = rsync

Port = 873

Hosts allow = 192.168.0.0/24

Use chroot = no

Max connections = 200

timeout= 300

PID file =/var/run/rsyncd.pid

Lock file =/var/run/rsync.lock

Log file =/var/log/rsyncd.log

[Asling]

Path =/home/rsyncdata

Comment = rsync files

Ignore errors

Read Only = False

List = no

Auth users = Rsync_backup

Secrets file =/etc/rsync.password

Example: Pull file

avoid the need to enter a password when performing rsync transfers (common in timed task scripts):

Add--password-file=
