What to expect

Backups designed around recoverable files

Read before installing: Duplicacy Web Edition offers a 30-day trial for backup operations. After the trial, creating backups requires an appropriate license; restore, check, copy and prune can be used without that backup license, per developer terms.

▣

Local-first management

Web Edition runs a local browser-based interface by default. You control which folders and destinations to use.

☁

Your storage choice

Use supported local or cloud backends, test the connection, and keep an independent offsite copy.

⬡

Deduplicated history

Duplicacy stores backup revisions and uses deduplication to avoid unnecessary repeated storage.

↺

Recovery is the goal

Find the right Backup ID, choose an earlier revision, and restore to a separate test directory.

◷

Scheduled checks

Combine backup, check, copy and prune jobs carefully, with retention and status monitoring.

⛨

Credential clarity

Understand how the Web master password differs from the backup-storage encryption password.

A straightforward start

Four steps to a verifiable Windows backup

1. Choose a source

Select actual Windows folders—not shortcuts or online-only placeholders.

2. Choose independent storage

Create a local or cloud destination, and keep your encryption password safe.

3. Run the first backup

Use a distinct Backup ID and check the job log when the initial revision completes.

4. Restore a test file

Pick a revision and recover a sample to a separate directory before trusting the backup.
