How to keep track of backups

What is it for?

The product does not make backups: it records the ones you made outside it, checks that they are intact, and warns you when one is missing. The screen says so: “Make the backup outside the program, calculate its checksum with “sha256sum” and register it here. The register only records and verifies; it does not make copies.”

When to use it?

• After each backup, to register it with its checksum.
• To check an old backup against the stored checksum.
• To see how many days the company has gone without a backup.

Where to find it?

Accounting › Configure › Security and data › Backup log and Backup alerts.

Before you start

Your profile is Certified accountant or system administrator. You need the backup already made and the SHA-256 checksum of the file (the sha256sum command). Done on 1 November 2026, with a fictitious backup.

How to use it

1. Open Accounting › Configure › Security and data › Backup log. With no records, it says “No backup registered yet”.
2. Click New. Done On opens with the current date and time and Scope with Database and files.
3. Type the Size (bytes), the SHA-256 checksum (64 characters, 0-9 and a-f) and Stored at (where the backup is). Save.
4. To check the backup later, open the record and click Check. Type the checksum of the stored backup, or choose the file, and click Compare. The state becomes Checksum matches or Checksum does NOT match.
5. Open Backup alerts to see the Open alerts.

Expected result

The record has Result Good and the message “Backup record created”. In the demo, the Alerts screen had an Open alert dated 30/10/2026: “No backup is registered for company Empresa Demonstração, Lda.”.

Important notes

• The record does not prove that the backup restores. It only proves that the file is the same: test a restore from time to time, outside the program.
• Pending validation on screen: the comparison (Compare) through to the end and the automatic closing of an alert after registering a backup.

Common problems

“a backup that was made needs its SHA-256 checksum”

• Message: “a backup that was made needs its SHA-256 checksum (64 characters 0-9, a-f). Calculate it on the stored copy with “sha256sum <file>” and paste the result.”
• Cause: you saved without the checksum, or with a checksum that does not have 64 characters.
• What to do: calculate the checksum on the stored backup and paste it into SHA-256 checksum.
