The Enterprise Server Edition Backup Client (ESE) reports an error that it is out of memory. This can occur during a backup or when calculating the size of the backup selection.
ESE loads all files and folders for each folder scanned into memory. It sorts the entries and then processes them one after another. Files are processed first before folders. Each entry's memory is released after it is processed.
To ensure continued operation we recommend providing the Backup Client service with 1GB for every 1 million items in the largest folder:
- In the toolbar, click the Options button
- Open the Performance -> Advanced Performance page
- Change the memory allocation of the Backup Service
- Save the changes by clicking OK
Note: This does not apply if files are well distributed on the file system - only if you have a large numbers of files and folders in a single folder.
