TokuDB Troubleshooting: Q & A

, and  | April 13, 2017 |  Posted In: MySQL, Technical Webinars


TokuDBIn this blog, we will provide answers to the Q & A for the TokuDB Troubleshooting webinar.

First, we want to thank everybody for attending the March 22, 2017 webinar. The recording and slides for the webinar are available here. Below is the list of your questions that we were unable to answer during the webinar:

Q: Is it possible to load specific tables or data from the backup?

A: Do you mean the backup created by TokuBackup? No, this is not possible. You have to restore the full backup to a temporary instance, then perform a logical dump/reload of the specific tables you want to restore.

Q: Since it is not recoverable when corruption happens, we have a risk of losing data. Is incremental backup the only option?

A: TokuBackup currently does not support incremental backup options. You can only create a kind of incremental backup if you copy and store the binary logs on a separate server, and then apply them on top of a previous full backup.
