I do not have an LVM volume in my CentOS7 setup, since RAID1 on XFS with LVM on top = possibly sub-optimal performance (as stated here, have a look at Andres719's comment)
However, I want to take a snapshot of atleast my DB and data folders for backup.
Is there a way I can get a snapshot of the folders without LVM.
(I may use 'cp', but then my production server will take a performance hit. Also, DBs will have to remain closed while cp does its work on, say, a 500GB folder)
