[tbsbdr]

Description

User Stories

• As an Admin I want to know what I need to include in my backups so that I can tailor a backup concept for my ocis installation.

Value

• Documentation

Acceptance Criteria

• Add documentation about:
  • config options that need to be kept forever stable (eg. storage-user-id-thingy or JWT-Token ...)
  • stores that can and can not be backed up (userlog, clientlog etc.)
  • data in var/lib/ocis/* eg. "please consider to backup the search index"
  • BLOBs: if you use an external blob store, this needs to be backed up externally

Definition of ready

• [ ] Acceptance criteria have to be defined
• [ ] All dependencies of the user story need to be identified
• [ ] Feature should be seen from an end user perspective
