s3 missing 1 file

[Adblu]

I have used aws cli tool to move couple of folders named: 2014, 2015, 2016 etc from root directory into

/2015/

into:

/images/2015/

command used:

aws s3 sync s3://path/to/bucket/2014 s3://path/to/bucket/2014/images --profile john@smith.com

When I moved them it seems that there is one file less in each bucket:

Before copying:

After coping:

Could you help me to understand this phenomena ?

Hi @Adblu,

Thanks for writing in! Just wanted to confirm before we move forward— did you use s3 cp or s3 sync? It sounded like cp from what you wrote, but just wanted to be sure.

@stobrien89 I have used sync. Here is a sample command:

aws s3 sync s3://path/to/bucket/2014 s3://path/to/bucket/2014/images --profile john@smith.com

Hi @Adblu,

Thanks for confirming! There are a few different reasons you may be missing files after a sync, some of which are mentioned in this issue. You can find a good overview of sync behavior here.

Anecdotally, s3 cp --recursive may be a better option for some users, depending on what they're trying to accomplish, and I think that may actually be a better option for you if you're just looking to copy all files from one directory to another. Let me know what you think!
