Hi Dan
The second link you refer to is, I believe, version-agnostic. (And s3cmd
is also version-unaware). So "an object" would expire after x days, rather
than "non-current versions of an object".
I've re-read the first description several times, and remembering that it
only applies to versioned buckets, still think that it is the correct xml
to specify how long non-current versions are retained (which is what I
want). It is also the exact same policy that I used without problem on
15.2.3, and also one that I use on AWS S3 itself....
Regards, Chris

Hi Chris,
Is it possible that this is the correct behaviour for NoncurrentDays
expiration?
AFAIK, the xml to expire *only* the versions older than x days is somewhat
different:

This is starting to look like a regression error
in Octopus 15.2.4.
After cleaning things up by deleting all old versions, and deleting and
recreating the bucket lifecycle policy (see below), I then let it run.
Each day a new version got created, dating back to 17 July (correct).
Until this morning when we went over the 18-day non-current expiration:
this morning all but the latest version of each object disappeared -
which is what happened the midnight following after our 15.2.3->15.2.4
upgrade.
So instead of a gently rolling 18-days of versions (on 15.2.3), we now
build up to 18 days after which all non-current versions get deleted (on
15.2.4).
Anyone come across versioning problems on 15.2.4?
Thanks, Chris

One object version got removed when it should not have.
In an attempt to clean things up I have manually deleted all
non-current versions, and removed and recreated the (same) lifecycle
policy. I will also create a new test bucket with a similar policy and
test that in parallel. We will see what happens tomorrow....
Thanks, Chris
