###### Sync core functions

## Rsync does not like spaces in directory names, considering it as two different directories. Handling this schema by escaping space.
|
|
## It seems this only happens when trying to execute an rsync command through eval $rsync_cmd on a remote host.
|
|
## So i'm using unescaped $MASTER_SYNC_DIR for local rsync calls and escaped $ESC_MASTER_SYNC_DIR for remote rsync calls like user@host:$ESC_MASTER_SYNC_DIR
|
|
## The same applies for slave sync dir..............................................T.H.I.S..I.S..A..P.R.O.G.R.A.M.M.I.N.G..N.I.G.H.T.M.A.R.E
