Good to know, thanks. Is it a bug that S3sync actually waits for way way more than 30 seconds sometimes?

[list_bucket max-keys 200]

Hi
I'm trying to back up a couple hundred gigabytes from a NAS drive on our company's network using S3sync. Some (most?) of the data show up in S3, so it is being backed up, but the script I run always gives this error:

S3 command failed:
list_bucket max-keys 200 prefix Restores/Restores/restore_2008_04_03_12_32_255159/C/TeamCity/ delimiter /
With result 500 Internal Server Error
99 retries left, sleeping for 30 seconds

S3 command failed:
list_bucket max-keys 200 prefix Restores/Restores/restore_2008_04_03_12_32_255159/C/TeamCity/bin/ delimiter /
With result 500 Internal Server Error
98 retries left, sleeping for 30 seconds


And on and on.....

What does the text in bold mean? How can I fix it? Is it due to a limitation on the length of the file path?
