LXD 3.1 Introduced a new backup API and ability to export containers using
Does this method allows incremental backup in which only the new deltas will be back up.
For example, a container contains three letters “X-Y-Z” was fully backed up yesterday. Today, the data is modified so now we have four letters “W-X-Y-Z”. If we then perform another full backup, it will copy the whole data “W-X-Y-Z”. But if we perform an incremental backup instead, it will only copy the “W” part of the data. Obviously, copying only the “W” part of the data will consume less disk space compared to copying the whole “W-X-Y-Z” data. Moreover, we already have the “X-Y-Z” part backed up previously, so we don’t need that part to be backed up again
