Hi Luca,
Thanks for the heads up. Isaac is coordinating a response from the
Research side.
I have one question for you: As you allow/encourage for more copies of
the files to exist, what is the mechanism you'd like to put in place
for reducing the chances of PII to be copied in new folders that then
will be even harder (for your team) to keep track of? Having an
explicit process/understanding about this will be very helpful.
Thanks,
Leila

Hi everybody,
as part of
https://phabricator.wikimedia.org/T201165 the Analytics team
thought to reach out to everybody to make it clear that all the home
directories on the stat/notebook nodes are not backed up periodically. They
run on a software RAID configuration spanning multiple disks of course, so
we are resilient on a disk failure, but even if unlikely if might happen
that a host could loose all its data. Please keep this in mind when working
on important projects and/or handling important data that you care about.
I just added a warning to
https://wikitech.wikimedia.org/wiki/Analytics/Data_access#Analytics_clients.
If you have really important data that is too big to backup, keep in mind
that you can use your home directory (/user/your-username) on HDFS (that
replicates data three times across multiple nodes).
Please let us know if you have comments/suggestions/etc.. in the
aforementioned task.
Thanks in advance!
Luca (on behalf of the Analytics team)
