Can I trust ReadyNAS Amazon Cloud sync?

I have ReadyNAS Amazon Cloud sync set up.  I recently got the following error 

 

ERROR: Failed to upload /data/VideoEditor/Samsung SSD 850 PRO 1TB_full_b1_s1_v1.tib. Please check the file path name. Amazon Cloud Drive is case insensitive.Change the file path name and try again..

 

The file is now actually on my Amazon drive with the correct length.  Is it good now.   When looking at detail fvamazon.log, there are MANY messages such as 

 

__acd_io_generic_readwrite: acd io status = 409, retry = 4

Question - can I trust that the error was corrected automatically and the file is good?   BTW - 45GB file so LONG upload but under the Amazon 50GB limit.
