Spectrum Protect 8.1.11 client has the fix so this should not be an
issue for Jonathan. Probably best to open a help case against Spectrum
Protect and begin the investigation there.
Also the fix is to stop an unchanged file with an ACL from being backed
up again, but only one more time.
I suspect we where hit with that issue, but given we only have ~90GB of
files with ACL's on them I would not have noticed. That is significantly
less than the normal daily churn.
This however is an issue with the *restore*.
Everything looks to get restored correctly even the ACL's. At the end of
the restore all looks good given the headline report from dsmc. However
there are ANS1589W warnings in dsmerror.log and dsmc exits with an error
code of 8 rather than zero.
Will open a case against Spectrum Protect on Monday. I am pretty
confident the warnings are false. The current plan is to do carefully
curated hand restores of the three afflicted users when the rest of the
restore if finished to double check the ACL's are the only issue.
Quite how the Spectrum Protect team have missed this bug is beyond me.
Do they not have some unit tests to check this stuff before pushing out
updates. I know in the past it worked, though that was many years ago
now. However I restored many TB of data from backup with ACL's on them.
JAB.
