Full Discussion: I need help setting up LVM snapshots on Ubuntu 16.04
Operating Systems Linux Ubuntu I need help setting up LVM snapshots on Ubuntu 16.04 Post 302981187 by rbatte1 on Thursday 8th of September 2016 06:53:24 AM

The creation of snapshot is usually with lvconvert for Linux systems. Others use a variety of other LVM commands.

Does the database not include the hot-backup functionality itself? It would be better to use that if you can. Have a look at Backup and Restore Overview - MariaDB Knowledge Base to see if that provides a better plan.

The problem you will have with LVM snapshots is being sure you have the correct definition of your process. The phrasing can be confusing in what it delivers and how. If you have a high-rate update database then some snapshots can expire before your backup completes.

Do you want to really make a copy of the LV, mount that elsewhere and backup from there? You might have a problem in ensuring that the snapshot is a true reflection of a point in time if there are multiple LVs in use for the DB.

Is this the only way?
