I have never seen an article or reference regarding re-tensioning LTO media.
In fact Quantum answered a similar question:
"Retensioning is not needed on single hub media, such as DLT and LTO. Dual hub
media requires retensioning after it has been dropped as the tape path because
it can be skewed between the two hubs. Since DLT and LTO media have a single
hub, the tape is wound through a path within the drive onto an internal hub.
This eliminates the problem with skewing."
A reliable industry source. You cannot apply general magnetic tape information
to LTO.

Hi,
As far as I have read there is a recommendation LTO-*
tapes to be physically rewind from start to finish and
back every now and then to release physical tension.
This tape retention has a different meaning from the
term "retention" in Bacula (if I understand correctly).
Also tapes have limited (although quite long) age and
same applies to write cycles.
My question is:
Does Bacula provide any means to monitor and service
all these? Or what recommendations would you give?
