Different file sizes for same export

    Howdy!

    Yesterday I’ve created an export of my staging environment (using AI1WM & Multisite Extension), which was 545.70 MB big.After making a few minor changes to the site, e.g. create a new page template and added a handful of custom meta fields, I’ve created an export and was surprised to see that the export had a file size of approx. 900 MB. The files that I created might have a total file size of 10 MB max. For the previous hours, I’m trying to troubleshoot this and found out that every export I run on my development environment has a different file size. The following exports had been created:

    2:33pm -> 886.30 MB
    5:25pm -> 899.30 MB
    5:29pm -> 900.90 MB
    5:44pm -> 821.80 MB
    5:48pm -> 899.30 MB
    6:06pm -> 901.00 MB

    After stumbling upon https://traktor.servmask.com/ I was able to look inside exports and found out that this issue seems to be caused by the file database.sql, which is located in the root folder.

    How is it possible that I create multiple exports of the identical system and receive exports with different file sizes? While creating the exports I haven’t touched the WordPress site at all. Also, the database and file size of the project remain the same throughout all exports. The project uses a disk space of 430.80 MB and the database has a file size of 121.28 MB. Yet, the file database.sql within the export has a file size between 397.66 MB and 473.11 MB, while the database.sql file of the original export yesterday had a file size of only 130.66 MB.

    Does this issue make any sense to you?

    It is difficult to answer exactly what is causing the difference.
    We could run a diff between the two files and find out what is different.

    WordPress has this feature called Transients API – it allows for caching data that is stored in the database to expire over time. https://codex.www.ads-software.com/Transients_API
    It will be my first guess.

    While you are not doing anything on the site, there are wp-crons that might be running and doing things in the background that you are not aware.

    If you want to find out exactly what is causing this, reach over to support at servmask.com
