Backblaze: preparing a recoverable backup
By the AXELITES team
Choosing cloud storage is not enough to organise backups. You need to know which data to protect, how often to copy it and how to retrieve it after an error or failure. This Backblaze resource places the storage service within a protection strategy suited to the company's applications.
Define the data and loss scenarios
The scope may include files, databases or configurations needed to restart an application. Distinguish what can be recreated from what would be lost. Scenarios to examine include accidental deletion, failure and data corruption. This analysis defines the frequency and retention of copies before deciding how to use Backblaze within the chosen backup arrangement.
Organise access and retention
A copy must remain available when the primary environment encounters a problem. The permissions used to create and delete it therefore deserve particular attention. Retention depends on recovery needs and the volume involved. When cloud storage is integrated into the setup, its location, transfers and selected offer's terms must also be examined to understand the technical dependencies and costs associated with retrieving data.
Test a complete restore
The presence of files in storage does not prove that an application can restart. A test must verify copy integrity and the operations required to restore a usable service. It also identifies missing access or knowledge. AXELITES presents Backblaze as an option for backup strategies; the quality of the setup depends on its configuration, monitoring and the ability to perform this restore in the real context.
Frequently asked questions
- Does synchronisation replace a backup?
- Synchronisation can replicate an unwanted deletion or modification. A backup strategy must make it possible to retrieve a relevant earlier state. Examine retained versions, their retention periods and access rights, then verify recovery in a real case.
- What should be tested first?
- Start by restoring the data essential to an important service. Check that it is consistent, access works and the application can use it. The test must include necessary manual operations, not just downloading a copy from storage.
