Hello,
What is the best way to set up a daily live snapshot for all VM, and have the possibility to recover, for example, a specific VM to a specific day?
Each snapshot you create make reads and writes slower, as qemu has to lookup data through the entire chain.
When we take a snapshot, we create a new file (or block device) and make the new file the active layer of the chain.
I'm not sure how much this is going to slow you down exactly, but I can tell you that there are also incremental backups to look into.
checking, thanks!
