hi, i have a network which is not connected to the internet and i want to use Nexus OSS v3. back in v2, i have installed a server in a computer connected to the internet, download what i needed, copied the blob store folder and just rebuilt indexes. i v3, the only thing i can do is to backup and restore but i have to backup everything according to the documents and that includes “security” which i don’t want to backup. i want to use active directory and i do not want to destroy it by restoring the db. any ideas ?

The working directory in NXRM3 is portable same as NXRM2, it’s just the files are in blobs rather than storage. Because of this, I suspect you could copy over everything but the /db/security folder and may be OK. That is assuming you want 0 security things copied over (users, user tokens, privileges, roles, etc). Otherwise I don’t think there’s a way to do what you want. The solution I think would probably benefit you is [https://issues.sonatype.org/browse/NEXUS-11468](https://issues.sonatype.org/browse/NEXUS-11468) which is not developed yet. You can follow that if that’s the case and no-one else has any ideas. I believe the feature is in preliminary discovery. I should also disclaim, I haven’t tried the above suggestion. Definitely back up your system before trying it (or test it out in a test system first). -Joe ---

Hi Joe, thank you for your reply.you have just confirmed what i suspected. i will give a try to your suggestion although the documentation states that i should restore all 3 DB’s together. Udi ---

To be clear, I was not suggesting a restore just a move. Restoring all the DBs at once is our recommended strategy. Good luck! -Joe ---
