DongDong,
I see two possible reasons:

1. Your retention policy expires the version before the maximum count
"versions data exists" is reached. If the retain-extra value is set to
a low number (like 4 days) and you change the file every 3 days, this
behaviour would be as expected.

2. You forgot to activate the policy set. You changed the "versions
data exists" value, but it didn't become active. Check the settings
with "q copy" and see whether the settings made their way to the
active copy group.


Good luck,
best regards,
Michael Bartl
