###### 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
