Incremental backups for some domains show the size of the full backup

Symptoms

Incremental backups for some domains show the size of the full backup. Or all incremental backups for a domain have the same size despite the fact nothing was changed on the server, thus, incremental backup size should be different.

Cause

This is bug with ID #PPPM-5447. Fixed in Plesk Onyx 17.0 Update 16.

Resolution

Update to the latest version using Plesk autoinstaller .

If an upgrade is not possible, apply the custom fix:

1. Connect to the server via SSH

2. Download the custom fix and unpack it:

   # wget https://support.plesk.com/hc/article_attachments/115000539025/PleskX.tar
   # tar -xfv ./PleskX.tar

3. Save the original file:

   # cp /usr/local/psa/PMM/agents/PleskX/PleskX.pm{,.backp}

4. Place the unpacked PleskX.pm file to /usr/local/psa/PMM/agents/PleskX/ directory:

   # mv ./PleskX.pm /usr/local/psa/PMM/agents/PleskX/PleskX.pm
