[drive.rs] Subject: [pbs-devel] [PATCH proxmox-backup v2 2/4] api/tape/inventory: optionally try to restore catalogs X-BeenThere: pbs-devel@lists.proxmox.com X-Mailman-Version: 2.1.29 Precedence: list List-Id: Proxmox Backup Server development discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 06 Oct 2022 11:36:13 -0000 in a disaster recovery case, it is useful to not only re-invetorize the labels + media-sets, but also to try to recover the catalogs from the tape (to know whats on there). This adds an option to the inventory api call that tries to do a fast catalog restore from each tape to be inventorized.
