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:
-
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 pzstdoption 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
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
