we recently installed 2 IBM TS4300 (one in each Datacenter) with LTO7 drives an i am really satisfied with the performance and veeam integration.
Our main backup to disk window is during night time, at about 10AM tape jobs pick up new restore points and put them on tape. Allowed window for tape jobs is from 10AM to like 8PM. Since execution window for all tape jobs is the same, drives are of course busy from time to time, resulting in veeam spamming errors about it.
To me a drive busy event is not an error if the job is able to backup the new restore points in its defined time window or after a defined amount of retries.
Is there any way to work around this error generating behaviour?
