Hello, A big thank you for your tips ! I have misunderstand this parameter and not set because some files are bigger than 50gb and not want to split them but it's like a minimal file size and create bigger blocks on the tape. It solve my issue and run really longer :)
- My version is 9.4.2 seem not too old and new versions 10/11 seem mainly change cloud storage parameters but may be missed something about tape storage - I can't verify if batch mode is active but run dbcheck with -b (batch mode) return me results without error so should be enable and good - I force Spool Attributes parameter manually to yes for be sure - increase Minimum/Maximum block size to 524288 (512k) help to use more bandwidth ~180 to ~300mo/s - It work with 15G but I will try with 45G most files are huge and restore speed isn't so much important only for disaster recovery.
