 * We have several websites using BackWPup and we typically do daily and weekly 
   backups. We continue to get the following errors:
 * WARNING: There was an unknown error when uploading the file.
    ERROR: Uploaded
   file size and local file size don’t match. ERROR: Step aborted: too many attempts!
   ERROR: Job has ended with errors in 9 seconds. You must resolve the errors for
   correct execution.
 * WARNING: Could not look up the file session.
    WARNING: The file could not be 
   uploaded. ERROR: Uploaded file size and local file size don’t match. ERROR: Job
   has ended with errors in 113 seconds. You must resolve the errors for correct
   execution.
 * These errors only occur sometimes, and sometimes the backup runs smoothly.
 * Please let me know if there is additional information you will need to help me
   fix these errors. Thank you.

 * Hi [@thomasjlamb](https://wordpress.org/support/users/thomasjlamb/)
    That really
   a server network issue( network unstable / drop connection or something like 
   that), that why the issue not always happens.
 * Other users also reported back this happens because of network issue too: [https://wordpress.org/support/topic/warning-could-not-look-up-the-file-session/](https://wordpress.org/support/topic/warning-could-not-look-up-the-file-session/)
