One of our customers told me about some serious problems with his tape backup jobs.
Some of them are failing with the above error-message.
Also the error messages appeared on different tape types. (LTO6 and LTO8). On demand the customer told me that he installed an additional LTO6-Drive in his library, to restore old tapes to new ones.
And thats the point – cause this configuration is not supported by Veeam –> Supported Devices and Configuration:
Veeam Backup & Replication tried to read LTO-8 tapes with the LTO-6 drive, which is just not possible.
Veeam Backup & Replication supports Linear Tape-Open tape libraries starting from generation 3 (LTO3) or later:
- Physical libraries, standalone drives and virtual tape libraries.
- Partitions of the physical or virtual tape libraries presented to the Veeam backup server.
Within a library partition, only one generation of LTO drives are supported.
You can either split up the library into two logical libraries were the LTO-8 drive can only access LTO-8 tapes, and LTO-6 drives only can access LTO-6 drives, or you just disable one of the drives in Veeam Software.
