 * Hi [@olgagutzler](https://wordpress.org/support/users/olgagutzler/) ,
   It seems
   like your debug code contains a failed backup process, rather than a migration
   attempt. Regarding this: your backup failed during database export, mostly due
   to its huge size.
 * In first place I’d recommend you to perform full cleanup and optimize all your
   tables.
   You can do that easily with help of free and simple plugin.Check it out:
   [https://wordpress.org/plugins/advanced-database-cleaner](https://wordpress.org/plugins/advanced-database-cleaner)–
   Cleanup won’t remove anything that is in use, so, no worries.
 * Then, follow these steps carefully:
    1.  Download and install “Advanced DB Cleanup” plugin
    2.  Do full Cleanup and optimize all tables using Advanced DB Cleanup plugin
    3.  After that you can already remove mentioned cleanup plugin if you wish
    4.  Go to Backup & Migration plugin settings
    5.  Open “Other options” section
    6.  Disable PHP CLI checking: [https://prnt.sc/1sljr31](https://prnt.sc/1sljr31)
    7.  Change backup method: [https://prnt.sc/1s1ofpa](https://prnt.sc/1s1ofpa)
    8.  Enable database batch export: [https://prnt.sc/bn7MjTUxHuEe](https://prnt.sc/bn7MjTUxHuEe)
    9.  Save “Other options” section
    10. Force to end both processes (troubleshooting): [https://prnt.sc/1trv1tm](https://prnt.sc/1trv1tm)
 * Right after the last step, you can run the backup process once again.
 * Let me know if that resolves your issue 🙂
   Thank you!
