Subject: [PATCH] conf: backup: Store incremental backup checkpoint name
per-disk
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
In preparation to allow heterogenous backups store the 'incremental'
field per-disk and fill it by default from the per-backup field.
Having this will be important once we'll want to allow incremental
backup working while hotplugging a new disk.
