Kaption can update an encrypted backup of your WhatsApp chats every hour, adding only what changed. How it runs, what it needs, and what each plan includes.
Kaption AIUpdated November 9, 2026WhatsApp backs up your phone once a day, once a week or once a month, depending on your setting. If you lose the phone at 6 p.m., everything since the last backup is gone with it.
Kaption can keep an encrypted backup of your WhatsApp chats current every hour, from your computer. This article explains how that works, what it needs to keep running, and what each plan includes.
Updated November 2026
Kaption Backups keeps one password-encrypted backup file in a folder you choose. With continuous backups on, Kaption checks every hour and adds only what changed: new messages, edits, deletions and new media. If nothing changed, nothing is written.
It works in WhatsApp Web with the Kaption extension for Chrome and Edge, and in the Kaption desktop app for Mac and Windows.
Because only the new part is added, a cloud app syncing the folder (iCloud Drive, Google Drive or OneDrive) mostly has the new part to move, not the whole file.
You can also press Back up now at any time. The status card then shows the progress, and when it ends, "Backed up just now" with the file size.
Hourly backups run while Kaption is running:
Two things can pause it:
So this is close to automatic, but not "set and forget". Glance at the Backups card now and then. It shows when the last backup ran.

You set the backup password when you set up continuous backups. It must be at least 10 characters. Kaption's servers never receive the file or the password. Nobody, not even Kaption, can open the backup without it, and there is no recovery.
You don't type the password for each hourly run. You type it to open the backup.
Choose View backup. The backup opens read-only in a new tab, laid out like WhatsApp, with search across every chat and voice-note transcript, and filters for groups, media and transcripts.
