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?

pbuilder-dist-simple
PBUILDER-DIST-SIMPLE(1) General Commands Manual PBUILDER-DIST-SIMPLE(1)
NAME
pbuilder-dist-simple - simple multi-release pbuilder wrapper
SYNOPSIS
pbuilder-<dist> operation [...]
DESCRIPTION
pbuilder-dist-simple is a wrapper that makes it easy to use pbuilder with chroots for many different Ubuntu distributions. If you need
more features than pbuilder-dist-simple provides, have a look at pbuilder-dist(1).
USAGE
Create one symlink to pbuilder-dist-simple for each distribution for which you want a build environment, naming them like "pbuilder-lucid",
"pbuilder-natty", etc.
Replace operation with the action you want pbuilder-dist-simple to do (create, update, build, clean, login or execute).
EXAMPLES
pbuilder-natty create
Creates a pbuilder environment for Ubuntu Natty.
pbuilder-lucid update
Updates an existing Ubuntu Lucid environment.
pbuilder-lucid build ./sample_1.0-0ubuntu1.dsc
Builds the specified package on an already existing Ubuntu Lucid environment.
FILES
By default, pbuilder-dist-simple will store all the files it generates in ~/pbuilder/. This can be changed by modifying the BASE_DIR value
on the top of the script to any other directory you want. If the directory doesn't exit, it will be created at runtime.
SEE ALSO
pbuilder(1), pbuilderrc(5), pbuilder-dist(1)
AUTHORS
pbuilder-dist was originally written by Jamin W. Collins <jcollins@asgardsrealm.net> and Jordan Mantha <mantha@ubuntu.com>, and this man-
page by Siegfried-A. Gevatter <rainct@ubuntu.com>.
