Purpose
Jira's index snapshot files are created in a compressed format. Starting with Jira 7.12.0, the default algorithm is Google's Snappy (.tar.sz). It was chosen aiming very high speeds and reasonable compression.

This can be customised to tarball (.tar) or Zip (.zip).
Solution
Follow these steps in order to change the compression method. Repeat the steps for all Jira Data Center nodes:
- Edit the jira-config.properties file under the JIRA_HOME directory. If the file does not exists, create it. See: Edit the jira-config.properties file in Jira server.
- The compression method used can be configured with the jira.index.snapshot.copy.archiver application property. Add the following line to the file. The values could be either snappy, zip or tar:
jira.index.snapshot.copy.archiver = snappy|zip|tar- Restart the node for the changes to take effect.
The chosen algorithm will reflect in the size of the compressed snapshot file and how fast the file is created. Ensure to validate it on a staging environment first.
