📌 Task summary

Increase the boot disk size of Jellyfin

📋 Task details

Since version 10.11.0, Jellyfin has “Internal Backup & Restore Support”.

This feature requires at least 5 GB of free space.

[ERR] Error processing request. URL "POST" "/Backup/Create".
System.InvalidOperationException: The backup directory '/var/lib/jellyfin/data/backups' does not have at least '5GB' free space. Cannot create backup.

To allow users to use this feature, the size of the boot disk should be increased to 16 GB or, preferably, 32 GB.
In my Jellyfin installation, the first backup takes up ~1.5 GB, with all options enabled and 12 MB only for the database.
