Is it safe to running multiple instances of rsync together

backuprsync

I'm wondering if its safe to use multiple rsync instances with the same command line to backup the same directory on the local server to the same directory on the remote server? basically if I ran the command below 3-4 times in parallel would it help speed things up? The recieving server is using rsyncd.

rsync -av /home/directory/ backups@1.1.1.1::Home

No. You can break it up into multiple commands, excluding or specifically including directories, but running the same command several times will result in a mess (especially with the rsync temp files).
