What is 'thin provisioning' in enterprise storage for document imaging systems?
Answer: Allocating storage capacity on demand rather than reserving all space upfront
Thin provisioning allocates storage dynamically as data is written rather than reserving the full amount upfront, improving utilization efficiency in document repositories.
In a disaster recovery plan for document imaging, what does 'RPO' stand for and what does it measure?
Answer: Recovery Point Objective — the maximum acceptable data loss measured in time
Recovery Point Objective (RPO) defines how much data loss is acceptable by specifying the maximum time interval between the last backup and a potential disaster.
Which protocol is most commonly used to access object storage via a web-based API in cloud document imaging solutions?
Answer: REST/HTTP with S3-compatible API
RESTful HTTP APIs, particularly Amazon S3-compatible interfaces, have become the standard for accessing object storage in cloud-based document management systems.
What is a 'storage snapshot' and how does it benefit a document imaging system?
Answer: A point-in-time copy of storage state that enables fast recovery without full backup restoration
A storage snapshot captures the state of a volume at a specific moment, enabling rapid rollback to that point if documents are corrupted or accidentally deleted.
When evaluating storage for a high-volume document scanning operation, which metric most directly impacts how many documents can be written per second?
Answer: Write IOPS (Input/Output Operations Per Second)
Write IOPS directly measures how many individual write operations a storage system can handle per second, which is critical for high-volume scanning ingestion pipelines.
What does 'geo-redundant storage' provide in a cloud-based document imaging architecture?
Answer: Replication of data across geographically separated data centers for disaster resilience
Geo-redundant storage automatically replicates data to a secondary data center in a different geographic region, protecting against site-wide outages or natural disasters.
In document imaging storage planning, what is the '3-2-1 backup rule'?
Answer: Maintain 3 copies of data, on 2 different media types, with 1 copy stored offsite
The 3-2-1 rule recommends keeping 3 total copies of data on 2 different storage media types with at least 1 copy stored at a separate offsite location.
