Request for clarification on snapshot files #13

Closed whardier closed 2 years ago

whardier commented 3 years ago

Do the snapshot files store destroyed blocks when intercepting writes for a volume or do they store pending block writes that will be flushed after the snapshot is destroyed?

CodeImp commented 3 years ago

When a write request is intercepted, the old data is saved to the snapstore, and then a write request is executed.  Copy-on-Write   https://habr.com/en/company/veeam/blog/430770/  Use autotranslate :)
