S3 versioning costs: Where hidden capacity goes
Versioning is one of the most useful features in object storage and one of the most common causes of capacity that nobody can account for. The mechanism is ...

Object storage rebuilds: What affects recovery time?
Every storage system tolerates a defined number of simultaneous failures. What matters operationally is how long it spends at reduced protection after one ...

S3 request performance: Why throughput is not enough
Object storage is usually specified in gigabytes per second, which suits the workloads it was first adopted for. Backup streams and media archives move large ...

Backup anomaly detection: Which storage signals matter?
Backup infrastructure sees the whole estate every night, which makes it an unusually good vantage point for noticing that something has changed. Most ...

Backup retention changes: Preventing silent exposure
Deleting a backup is an event. Shortening a retention policy is a settings change, and it produces the same outcome more quietly: copies expire on their new ...

Ransomware recovery exercises: What to measure
Most organizations run some form of recovery exercise, and most produce a report that says it went well, with a list of observations and a note to repeat next ...

Backup isolation testing: Can production reach copies?
Most backup architectures include something described as isolated: an air gapped copy, a segmented repository, a vault. The description is usually accurate ...

Backup storage failure: Recovering during a rebuild
Recovery plans assume the backup repository is healthy. That assumption holds most of the time and fails in exactly the circumstances that produce a recovery: ...

Mass restore planning: Recovering hundreds of workloads
A restore test usually covers one system. It confirms the backup is valid, the procedure works and the timing is acceptable, and it says almost nothing about ...
