Tony, >From what I recall having worked with snapshots a while ago, you would want export-diff to achieve a differential export. "export" will always go for a full image. -- Alex Gorbachev https://alextelescope.blogspot.com On Sun, Aug 27, 2023 at 8:03 PM Tony Liu <tonyliu0592@xxxxxxxxxxx<mailto:tonyliu0592@xxxxxxxxxxx>> wrote: Hi, Say, source image has snapshot s1, s2 and s3. I expect "export" behaves the same as "deep cp", when specify a snapshot, with "--export-format 2", only the specified snapshot and all snapshots earlier than that will be exported. What I see is that, no matter which snapshot I specify, "export" with "--export-format 2" always exports the whole image with all snapshots. Is this expected? Could anyone help to clarify? Thanks!
