No, FlexRAID in Snapshot mode can deal with added, renamed and moved files just fine.
In FlexRAID’s implementation of Snapshot RAID:
– renaming, moving data does NOT invalidate the parity
– adding data does NOT invalidate the parity (existing data and parity are in sync, but new data will not be protected until an update is run)
– editing and deleting data does
– when the RAID is out of sync, you stem to lose data up to the amount of changed data (multiple parity configurations further minimize that effect)
Of course, this topic is irrelevant to Real-Time parity.
