Read-only, can be slowRead the Restore Drill Validation Report
You need to pull the key pass, RPO, RTO, checksum, and file-count lines from a restore drill report.
Command
REPORT=/srv/backups/site/reports/restore-validation-2026-06-25.txt && grep -E 'status=|rpo_minutes=|rto_seconds=|checksum=|file_count=' "$REPORT"Before you run this
System impact: Read-only. Can create load on large logs, directories, filesystems, or process tables.
When not to use it: Do not use a report as a substitute for running the restore and validation commands.
Expected output
Key report lines showing status, RPO, RTO, checksum, and file-count results.
System impact
Read-only, can be slow. Nothing changes. The command reads the report.
Scope this to the smallest useful path or service on busy systems.
Recovery / rollback: no state is changed.
When to use it
Use after a drill to capture the validation signals people will ask for during an incident review.
When not to use it
Do not use a report as a substitute for running the restore and validation commands.

Read the Backup Manifest
The manifest should say what backup you are about to trust.

Find Missing Files in an Old Backup
The fastest failed restore drill is the one that finds missing critical files early.

Extract a Backup Into a Restore Sandbox
A restore drill should write to a sandbox, not production.
BACKUP_ROOT=/srv/backups/site RESTORE_SANDBOX=/tmp/linuxoneliners-restore/full && rm -rf "$RESTORE_SANDBOX" && mkdir -p "$RESTORE_SANDBOX" && tar -xf "$BACKUP_ROOT/2026-06-25/site.tar" -C "$RESTORE_SANDBOX"
List Archive Contents Before Extracting
You can inspect a tar backup before it writes a single file.
BACKUP_ROOT=/srv/backups/site && tar -tf "$BACKUP_ROOT/2026-06-25/site.tar" | sed 's#^./##' | sort
List Restore Points Before a Drill
A restore drill starts by proving which backups actually exist.
BACKUP_ROOT=/srv/backups/site && find "$BACKUP_ROOT" -maxdepth 2 -type f -name MANIFEST.txt -printf '%TY-%Tm-%Td %TH:%TM %h\n' | sort -r

Use this as independent command practice: read the notes, predict the output, then compare it with the example before using a real shell.
