Question

How to unpack the contents of a Plesk backup?

Answer

Starting from Plesk Obsidian 18.0.40, GZIP compression used in the Plesk backups has been replaced with ZSTD compression to improve performance for backup and restore operations.

To unpack a TZST archive, follow these steps:

Directly on a Plesk server using tar

Connect to the Plesk server via SSH.
Create a directory where the backup is going to be extracted:

# mkdir /root/backup
Use the --use-compress-program pzstd option to unpack the archive:

# tar -xvf /var/lib/psa/dumps/domains/example.com/backup_logs_2111250004_2111290004.tzst -C /root/backup/ --use-compress-program pzstd

After downloading a Plesk backup file to Windows OS

Download and install the tzst compatible archive manager and use it to extract the files.

For example:

7-zip build with TZST support: https://github.com/mcmilk/7-Zip-zstd/releases/tag/v21.03-v1.5.0-R2
WinRAR v6.x: https://www.win-rar.com
