Problem description

While backing up PDF files, the backup completes with an error message "Internal error. (#100000001)" in the client logs.


The "Internal error. (#100000001)" is seen when the files not being backed have an incorrect modified date, which is either in distant past or in future.

The error is seen for the files with modification date of future or distant past. By design,  inSync Client  does not back up files with incorrect date or time.The error is also logged for password protected PDF files which inSync cannot read or access.

Traceback (inSyncclient.log)

Exclude non-essential files from backup

Exclude files which you do not require to be backed up from the backup list and subsequently, initiate a backup to see if the backup completes without any errors.

Check and resolve modified date and timestamp of the file

  1. Confirm if the modified date and time of the affected file is correct.
  2. Right-click on the PDF > Properties > General tab > Modified and  check if the dates (of +/- 20 years) format is correct.

  3. If the file has incorrect modified date of distant past or of future, correct the timestamp of the PDF file using tools from the following links:
  4. Start a fresh backup after appropriate values are restored for the date and time attributes of the PDF and check if the backup completes without errors.
  5. If the issue persists, please contact Druva Support for further investigation.
