Backup Build Failure for Large Files
When attempting to build a large backup, the process may fail due to Strato’s file size limitation (1–2GB). To bypass this restriction, try the following solutions:
Solution 1: Request a Server Setting Change
- Contact Strato support and request them to remove or increase the file size limit on your server.
- Once this restriction is lifted, you should be able to build the backup without issues.
Solution 2: Use File Filtering
- Exclude non-essential directories or large files in the file filter during the first step of the build process.
- After migration, manually move the excluded files to the new location.

Solution 3: Perform a Two-Part Install
- Use the two-part install method, which helps work around file size limits.
- Follow the step-by-step guide here: Duplicator Two-Part Install Guide
By applying these methods, you can successfully migrate large sites on Strato hosting while avoiding file size limitations.
