Depending on what a user is trying to accomplish, there might be a few bitmap cleanup actions that occur when an operation is finished that could be useful. I am proposing three: - NEVER: The bitmap is never synchronized against what was copied. - ALWAYS: The bitmap is always synchronized, even on failures. - ON-SUCCESS: The bitmap is synchronized only on success. The existing incremental backup modes use 'on-success' semantics, so add just that one for right now.

Subject: [PATCH] qapi: add BitmapSyncMode enum
|
|
|
|
Depending on what a user is trying to accomplish, there might be a few
|
|
bitmap cleanup actions that occur when an operation is finished that
|
|
could be useful.
|
|
|
|
I am proposing three:
|
|
- NEVER: The bitmap is never synchronized against what was copied.
|
|
- ALWAYS: The bitmap is always synchronized, even on failures.
|
|
- ON-SUCCESS: The bitmap is synchronized only on success.
|
|
|
|
The existing incremental backup modes use 'on-success' semantics,
|
|
so add just that one for right now.
