Can we still use the local Smart Mirror server if it loses connection with the Bitbucket cloud?

[Lloyd Langley]

We are looking to migrate our self-hosted Bitbucket (and Jira and Confluence) to the Atlassian cloud.  We are looking at having a local Smart Mirroring server and several questions are being asked.  Can you help?

1. Can we backup the Smart Mirror server and use it to recover in the event of a serious data loss?

2. If we lose connectivity between the Bitbucket Cloud and the local Smart Mirror server, can we still fetch from the Smart Mirroring server and continue working?

Many thanks for your advice.

Hello @Lloyd Langley,

Thanks for reaching out!

Can we backup the Smart Mirror server and use it to recover in the event of a serious data loss?

The Mirror stores all synchronized repositories locally just as a normal Bitbucket Server instance, so this article somewhat applies to a Mirror instance too. Specifically, DIY backup should work just fine.

If we lose connectivity between the Bitbucket Cloud and the local Smart Mirror server, can we still fetch from the Smart Mirroring server and continue working?

Unfortunately, not really. Mirror delegates authentication and authorization to Bitbucket Cloud, so whenever a user is trying to pull from the Mirror, it makes a call to the Cloud to authenticate and authorize the user against the repository in question. There's a bit of caching involved, so some requests might be served for a short time (configurable) after Mirror becomes offline, but in general the Mirror doesn't store or sync user/repository permissions and relies on the upstream.

Hope this helps. Let me know if you have any questions.

Cheers,
Daniil
