Resolve a bzfileids.dat File Error

Backblaze Computer Backup maintains a file on your computer called bzfileids.dat. When Backblaze Computer Backup backs up your files, it loads the bzfileids.dat file into RAM to run a checksum before uploading your files to the server. If you back up an extremely large number of files, or if your computer has used the Backblaze Computer Backup software for a very long time, the bzfileids.dat file may become too large to be fully loaded into RAM, prompting an error message. If you receive this error message, you can fix the issue by re-uploading all of your backup data.

Re-Upload your Backup Data

1. Uninstall Computer Backup.
2. Download a new trial version of Computer Backup, and install it.
3. Sign in to your Backblaze account.
4. In the left navigation menu under Computer Backup, click Preferences.
5. Click Delete Backup next to the name of the computer backup that is experiencing this issue.
   Your Computer Backup license is free to be reassigned after the backup is deleted.
6. If your Computer Backup license is not automatically applied to the new trial installation, click Overview in the left navigation menu and click Use License next to the name of the new installation.
