  • Product edition: inSync Client version 5.5

Problem description

The backup status on the inSync Client displays the following error:

Error: Failed to backup. Check log for details.



inSync starts to back up the EDRM Metadata attributes and the error usually points to the mtime of the file. There have also been instances where the mtime was correct, yet this error was displayed. When the mtime is negative, the Python API to format the time fails with an exception causing this backup failure. 


The following log excerpts are only examples. Date, time, and environmental variables may vary depending on the environment.
