Native and compression -
Our byte count to a DLT-S4 Tape is currently 665GB (native is 800GB and 16TB compressed) and we currently have Hardware compression enabled. I have with previous devices. such as SDLT600, experienced backup failures not much above their native capacity.
I would like to investigate if there is any way anticipate when the backups might start to fail due to native or compression restrictions but appreciate there is going to be data that is compressed on the fly (during backup) and also data that is pre-compressed which cannot be reduced in size any more.
I'm wondering if it is going to be a case of waiting for backups to fail or there is something I can do to preempt when Tape capacity is exhaused?
