As shown in the figure, I found that the size of my backup file dropped from 1.5G to more than 700M after March 15th. I don’t know what happened.
I used another test website I had, restored 700MB of archive, and backed it up again, and the downloaded backup was 2.6GB again. This confused me even more, because the logs of the two backups were almost the same, the only difference was that the test website was stored locally, and the previous website was backed up in Linode’s object storage.
