Amazon S3: s3cmd put ([Errno 32] Broken pipe)

by on under Linux
1 minute read

Recently I decided to use Amazon’s S3 as another location to store some of my server backups. However I found when testing that I was unable to upload my backup tarballs to S3. I ended up with the following errors.

ERROR: Upload of 'backup-20140731.tar.gz' failed too many times. Skipping that file.

The file I’m uploading isn’t huge (238MB). So it wasn’t the known limit of trying to upload files which are greater than 5GB.

[email protected]:backups$ ll
total 238M
-rw------- 1 jacob 238M Jul 31 06:00 backup-20140731.tar.gz

It seems that this is a common issue when uploading files to a new bucket. Something to do with the DNS propagation means it takes a little while before your bucket can successfully accept files. More info here.

After waiting a few hours running the same command completes successfully.
