Backup using rsync

rsync — a fast, versatile, remote (and local) file-copying tool.

Some of the additional features of rsync are:

  • support for copying links, devices, owners, groups, and permissions
  • exclude and exclude-from options similar to GNU tar
  • a CVS exclude mode for ignoring the same files that CVS would ignore
  • can use any transparent remote shell, including ssh or rsh
  • does not require super-user privileges
  • pipelining of file transfers to minimize latency costs
  • support for anonymous or authenticated rsync daemons (ideal for mirroring)


rsync [OPTION] [Source] [Destination]


[my-home@localhost ~]$ rsync -avz /home/my_home/mysql-11-10-2014.tar.gz /home/my-home/
sending incremental file list

sent 66 bytes  received 12 bytes  156.00 bytes/sec
total size is 355212048  speedup is 4554000.62

another ex:

[my-home@localhost ~]$ rsync -avz --progress /home/my_home/mysql-11-10-2014.tar.gz /home/my-home/
sending incremental file list
   355212048 100%   27.96MB/s    0:00:12 (xfer#1, to-check=0/1)

sent 355331398 bytes  received 31 bytes  28426514.32 bytes/sec
total size is 355212048  speedup is 1.00

Explanation for the [options] used above:

-a = Archive mode.
-v = Be verbose.
-z = Compress the data during transfer.
–progress = Show progress during transfer.

Access via remote shell:

rsync can be used over ssh, making the transfer just as secure as other existing alternatives for secure transfer of remote data, such as scp & sftp. Since scp & sftp do not create incremental backups, and don’t sync the data between the source and the destination (but rather just copy the data, “as is”) – rsync should be preferred over these alternatives.

Pull: rsync [OPTION] [USER@]HOST:[Source] [Destination]
Push: rsync [OPTION] [Source] [USER@]HOST:[Destination]


[my-home@localhost ~]$ rsync -avz -e ssh --progress /home/my-home/

Tip when got trouble:

[my-home@localhost ~]$ rsync -avz -e ssh --progress /home/my_home/
ssh: connect to host port 22: Connection refused                                         
rsync: connection unexpectedly closed (0 bytes received so far) [receiver]                             
rsync error: unexplained error (code 255) at io.c(600) [receiver=3.0.6]

check the port ssh from the source. like mine was 6969 and use –rsh=’ssh -p6969′.

[my-home@localhost ~]$ rsync -avz --rsh='ssh -p6969' --progress /home/my_home/'s password:
