Once in a while we the backup stops with this error message without an obvious reason:

I got the same error.
"there was an error: unexpected EOF running backup on ops-manager tile:tile"

anyone found the fix for this or reason why it happens? i am yet to see a working full successful backup of opsman tile in PCF 1.10

@Pilot001
I have successful opsman backup for few days. all of a sudden once in a while I get this unexpected EOF error.

anybody figured how to prevent this from re-occurring. All the moment all i do is just re-run backup process w/cfops and hope will not run into unexpected EOF
