Function backup_job_create() creates a block job to backup a block device. The coroutine is started with backup_job_start(). We call backup_do_cow() for each write during backup. That function reads the original data and pass it to backup_dump_cb(). The tracked_request infrastructure is used to serialize access. Currently backup cluster size is hardcoded to 65536 bytes. |
