Subject: [pbs-devel] [PATCH proxmox-backup] docs: tape: clarify LTO-4/5 support
Date: Mon, 3 May 2021 11:27:46 +0200 [thread overview]
Message-ID: <20210503092746.6597-1-d.csapak@proxmox.com> (raw)
some features we need (e.g. READ POSITION long form) are only officially
available with LTO-5, but work on many LTO-4 drives, so move LTO-4 to
'best-effort' support.

Supported Hardware
------------------
-Proxmox Backup Server supports `Linear Tape-Open`_ generation 4 (LTO-4)
-or later.
+Proxmox Backup Server supports `Linear Tape-Open`_ generation 5 (LTO-5)
+or later and has best-effort support for generation 4 (LTO-4). While
+many LTO-4 systems are known to work, some might need firmware updates or
+do not implement necessary features to work with Proxmox Backup Server.
Tape changing is carried out using the SCSI Medium Changer protocol,
so all modern tape libraries should work.
