Automatic and Manual Sigma Data Backup

[Product_Support]

Issue

Which files can be safely backed up using automatic or manual methods?

Product Line

Satchwell BAS & Sigma

Environment

Sigma (All versions)

Cause

Backing up a live Sigma system is not recommended, as copying files that are currently open may compromise data integrity.

Resolution

To ensure a reliable backup process, follow these guidelines:

1. Files Safe to Back Up While Sigma Is Running
   The following directories contain archive data and can be backed up safely without shutting down the system:

   • C:\\Sigma\\Data\\ArchivedAlarms

   • C:\\Sigma\\Data\\ArchivedLogs

   • C:\\Sigma\\Data\\ArchivedTransactions

   ⚠️ Note: These files should only be removed for space-saving purposes. Sigma can be configured to access and view these archived files.

2. Files Requiring System Shutdown Before Backup
   For all other Sigma files, it is strongly recommended to shut down both the Sigma server and all clients before initiating a backup. This ensures that no files are open or in use during the process.

3. Restoring Data
   Data restoration must only be performed after the Sigma system has been completely shut down.

Additional Notes

• This guidance applies to both automatic and manual backup procedures.
• Always verify that the Sigma system is offline before handling non-archived files.
