The question
A
recovery point is the time represented by the copy you can actually restore. If the last usable backup is from Monday and the computer fails Thursday, changes since Monday may be gone. The goal is to choose a backup frequency that matches how quickly your important data changes.
Example
A student edits a thesis every day but plugs in an external drive once a month. That drive protects an older draft, not yesterday's work. A daily cloud backup with version history plus a separate periodic offline copy offers different recovery options. CISA's
backup-options guide discusses multiple copies and locations.
Make it useful
Write down the newest backup you have opened successfully and how much work changed since then. Increase backup frequency where that gap would be painful. Do not confuse a sync timestamp with a recoverable older version. The acceptable gap for family photos may differ from that for a daily work project.
