I encoutered the error  "The parameter is incorrect" while I was backing data in PI SMT.
2 files can't be backup: 1 file in %pihome%\log and 1 file in %pihome%\arc. Any suggestion?
It's possible you may be running into this known issue with compatibility issues with the VSS backup on PI Server 2012 and Windows Server 2012 R2. This is where I most commonly see this issue occurring. Can you tell us what version of the Data archive and OS you're running for the machine running into this issue?
Thanks a lot, Schmitz! I can back up easily after installed the KB2963918 hotfix.
