The decision
Count originals, previews, database data, logs, imports, exports and a working margin separately.
A bounded example
Measure a sample import before choosing storage. Preview jobs can change both disk use and background work.
Documentation
Use the relevant version of Nextcloud — Backup before changing a live service.
Checks before change
Keep a recovery route, work on an isolated copy when data is affected, and record observations rather than assumptions. Stop if an acceptance check fails.
Limits
Hoszen does not preinstall or operate applications, hold secrets, verify backups, promise capacity or confirm a payment or VPS delivery.
