The Actian/Pervasive database contains multiple .MKD files for the different records that make up a data file.

If an .MKD file is more than 2GB, then extended files are created with a file extension of ^01, ^02, ^03, etc.

The System Administrator Backup tool is excluding these extended files from the backup when you select the Data Only option.

An excludedFiles.txt gets added to the backup .zip file. This text file lists the excluded files.

We resolved this issue in version 25.1.

For versions before 25.1, use the All files options when creating backups through the System Administrator Backup tool.

When you want to back up only a specific company data folder, use the compress folder (.zip) option through File Explorer as an alternate method. You can also copy the folder as a backup.

Always verify and test that your backups are complete.

 NOTE: Restored data that's missing the extended data files may result in a Pervasive Status Code 13 error when you try to access that data.
