Copy GDB - Error 000260

ModernElectric

I am working with ArcMap 10.5.1 and ArcGIS Pro and recently, in the past few months, have been having issues using the Copy tool in my Python script and in ArcCatalog to copy my working GDB(s) from my local drive (C-Drive) to our network drivers (Y-Drive). The purpose of this is our network drives are backed-up each night versus the data on my local hard-drive. 

I have been getting ExecuteError: 000260: Failed to Copy.

Not sure why this has become an issue since I have not had a problem in the past. 

I can copy the GDB from location to location on my local hard-drive, but NOT from the local hard-drive to a network drive.

Any suggestions?

UPDATE

Talked to our IT Department who manages the networked drives, the particular directories I was writing to were compressed, unknown to myself. After they decompressed those directories, the ArcPy Copy Tool worked like a charm with no error code(s).
