Backup Strategy Questions

[Ken]

Hello,

I'm in the process of creating a backup strategy for our RavenDB databases, and I have a some questions that I haven't been able to find answers to.

1. The backup documentation (http://ravendb.net/docs/article-page/2.5/csharp/server/administration/backup-restore) indicates that "Only one backup operation may run at any given time." Is this server wide, or is it per database allowing us to backup all databases in parallel?

2. Our databases have several bundles installed. In the future we may add more or develop our own. We are also using custom Lucene.Net analyzers. Are there any special considerations we should be aware of for backing up and restoring with this configuration to ensure our bundles and analyzers continue to work?

3. It appears that Raven.Backup.exe backs up all databases in one operation. Is this correct? If so, does this include the system database?

4. What are the advantages and disadvantages of using VSS versus RavenDB's built-in backup mechanism. Is one recommended over the other?

Thank you in advanced.

1) Per database.

2) You need to make sure that your analyzers and custom bundles (including the exact versions, if there might be breaking changes) are available when you do a restore.

3) That is not correct, it backs up a _single_ database. 

4) We usually recommend to go with the built-in backup, it has been far more therally tested and worked on.

Thank you for your quick reply. It is much appreciated. A couple more questions for you. Under what conditions would we need to restore the system database? What kinds of data and/or settings are in there that might affect our ability to recover from some kind of failure? We are currently running version 2.5.2910, in case that makes a difference.

Thanks again,

Ken

The system database contains all the server side setup, that includes database locations, bundles, etc.

Backup status for all dbs, etc.
