###### 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 weval $rsyncCmd on a remote host.
## So I am using unescaped $INITIATOR_SYNC_DIR for local rsync calls and escaped $ESC_INITIATOR_SYNC_DIR for remote rsync calls like user@host:$ESC_INITIATOR_SYNC_DIR
## The same applies for target 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
