There is no silver bullet on how to protect this data, so it will depend on the application and whether it provides an API or a "dump" capability on your approach to protecting it. In very, very simple terms, you could "pause" a Docker container, snapshot the devices (disk or filesystem) where the persistent storage is held and you have the equivalent of a hardware based snapshot backup.

* For Spectrum Protect you need to use `--privileged=true`. From what I have worked out, DB2 needs this. I did find some notes on DB2 in docker [here](https://www.ibm.com/developerworks/data/library/techarticle/dm-1602-db2-docker-trs/index.html), and tried these options without using `--privileged=true` but DB2 still reported some errors.

I dont think it is an issue running SP in privileged mode, but if you do find a solution to have it run without full privileges, I would be interested ;)

* When defining your DISK based storage pools (or STGPOOLDIR for your cloud pools), remember the path to your "data" is `/data` inside the container. If you use another path, you will loose that data when the container is destroyed.

* You should be able to run many SP instances on the same host (or swarm) even at different version levels. In container, they can all respond to port 1500, and outside the container, they'll need to have unique ports eg: `-p 1501:1500`, `-p 1502:1500`, etc. (Just remember to think about resource requirements and potential resource contention.)

Technically it should work without problems, but if you are experiencing a problem, be prepared to recreate your environment on a physical host and validate that your problem still exists (and thus not a result of Docker or the implementation on Docker).

I have found that upgrading within a major release, eg: 7.1.0 to 7.1.1, 7.1.2 to 7.1.3, etc works transparently. Upgrading from 6 to 7 (I havent tried) and 7 to 8 (failed for me). Spectrum Protect is smart enough to realise that it has been upgraded and will do a one time schema update. However, DB2 needs thought, especially if there has been a major change in DB2 between SP releases.

I have found that upgrading within a major release, EG: 7.1.0 to 7.1.1, 7.1.2 to 7.1.3, etc works transparently. If upgrading that results in a version of DB2 changing (like v7 to v8) additional consideration needs to be made that has not yet been captured in my `upgrade` option below. (Upgrading from v7 to v8 failed for me because of DB2 issues that I wasn't able to resolve - DB2 changed versions between 7 and 8.)
