Adobe Analytics stores analytical data somewhere, may be in a database.
How to configure automatic data back-up and recovery of data?
In case this feature is not available, how to deal with the situation, where the AA data store crashes and the data is lost?
Appreciate your support.
Adobe takes care of all of that for you. If you are curious to see what Adobe's policy is on the matter, the following are several helpful reading materials: Data Availability, Security, and Recovery Whitepapers
If you would like to have data backups within your organization, you can request data feeds for each report suite: Analytics Data Feed
Thanks for responding with a very useful link.
