Question

Recover SQL database with directories only

Posted May 9, 2021 158 views
MySQL

Somehow my DO backups of my working were all corrupt – I had to revert from a backup and none of them would complete. Not looking for reason why now.

Using DO’s tools, I was able to boot a generic instance with the backup as a drive. I was able to go to the MySQL folder and download all the directories of all my databases. But, I can find no way to get them, or one of them, into a new instances database, which requires a .sql file to import.

Any bright ideas to get these directories into the form that I can import them please? Thank you.

Hi there,

I’ve faced that MySQL problem in the past with another provider. What I did to fix the problem was:

  • Created a fresh new server and installed the exact same MySQL version as the old one

  • Then stopped MySQL on that new server:

systemctl stop mysql
  • Again on the new server rename the /var/lib/mysql to /var/lib/mysql-backup:
mv /var/lib/mysql /var/lib/mysql-backup
  • Then copy the mysql folder from your backup to the freshly created server and add it to the /var/lib/mysql directory.

  • After that set the owner of the files and folders to the mysql user:

chown -R mysql:mysql /var/lib/mysql
  • Finally start MySQL and repair the tables if needed

Let me know how it goes.

  • Excellent idea. I may have thought to create the new server, but I wouldn’t have thought to create the same SQL version.

    Since many of the databases were separately backed up (with Akeeba), I have most sites online. I may vary from your instructions, to try an export of the one database I didn’t have well backed up. See if that imports after getting the .sql made.

    Many thanks. I’ll let you know.

    • Hi there,

      Ah yes, if you have the chance to export the databases in .sql format it would be a much cleaner solution.

      Hope that you get it all sorted!
