Read-only, can be slowList Newest Source Files Before Backup
You need a timestamp-sorted view of source files before comparing backups.
Command
find source -type f -printf '%TY-%Tm-%Td %TH:%TM %p\n' | sort
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 it as proof that backup contents match; pair it with checksums or rsync dry runs.
Expected output
A sorted list of source files with modification timestamps.
System impact
Read-only, can be slow. Nothing changes. The command reads file timestamps and paths.
Scope this to the smallest useful path or service on busy systems.
Recovery / rollback: no state is changed.
When to use it
Use before backup checks or when you need to understand recent source changes.
When not to use it
Do not use it as proof that backup contents match; pair it with checksums or rsync dry runs.
