You do not need to read every article in order. Pick the situation you are in, keep your actual observations, and stop where a required check has not been performed. Field notes, synthetic experiments and configuration guides have different scopes.
Will another service fit?
Start with a host observation, then separate memory pressure from a planned allowance.
- What fits on a 4 GB server?
See the limits of one shared-host snapshot. - Is your VPS short of memory, or just using it?
Collect available memory, swap activity and pressure over time.
What to leave with: Write down measured conditions and an explicit allowance; then try the memory calculator. A positive remainder is not a load-test result.
Where did the disk space go?
Identify the storage layer before changing logging or removing recovery points.
- The file is gone. Why is the disk still full?
Distinguish filesystem, inode and directory observations. - A new logging default does not change an old container.
Separate container output from application files and inspect effective logging settings. - Seven backups fit. The next one still needs room.
Budget the new backup and restore workspace before pruning.
What to leave with: Keep a source inventory and a peak-space plan. None of these guides authorizes pruning a live repository or truncating Docker files.
Can this job run unattended?
Define observable success, verify recovery and choose what happens after an overlap or a missing response.
- The checklist before “run it every hour.”
Use the backup acceptance sequence and blank run record. - Give a scheduled job the context it actually needs.
Make command lookup, input paths and required configuration explicit before scheduling. - Make a SQLite backup you can actually check.
Check the intended recovery point and representative application reads. - When the next job starts before the last one ends.
Choose skip, wait or bounded wait; distinguish waiting from execution time. - The request timed out. Did the write still happen?
Keep an ambiguous effect unknown until the receiver contract resolves it. - Check the release, not just the status code.
For a publishing job, verify the intended public bytes and preserve a guarded recovery path.
What to leave with: Complete one private manual record with evidence and remaining work before enabling a schedule. The separate Lab experiments do not validate your combined workflow.
Take the checklists with you
The free starter pack includes the manual automation and backup worksheets, the Docker logging change checklist, two alternative Compose fragments and a daemon settings example. It contains no application image, credentials or deployment script. Adapt the files and fill them with real observations.
Examples are not universal recommendations. JSON/YAML parsing does not establish Engine acceptance, and completing a worksheet does not prove recovery or unattended operation. Read how we distinguish evidence and guidance.
