Troubleshooting Import Job Problems
Sometimes files fail to import into Amazon S3. If the following issue occurs, try the actions specified
to resolve your issue. If a file fails import, you might need to try importing it again. Importing it again
might require a new job for Snowball Edge.
Files failed import into Amazon S3 due to invalid characters in object names
This problem occurs if a file or folder name has characters that aren't supported by Amazon S3. Amazon
S3 has rules about what characters can be in object names. For more information, see Object Key
Naming Guidelines.
Action to take
If you encounter this issue, you see the list of files and folders that failed import in your job completion
report.
In some cases, the list is prohibitively large, or the files in the list are too large to transfer over the
internet. In these cases, you should create a new Snowball import job, change the file and folder names
to comply with Amazon S3 rules, and transfer the files again.
If the files are small and there isn't a large number of them, you can copy them to Amazon S3 through
the AWS CLI or the AWS Management Console. For more information, see How Do I Upload Files and
Folders to an S3 Bucket? in the Amazon Simple Storage Service Console User Guide.
Troubleshooting Export Job Problems
Sometimes files fail to export into your workstation. If the following issue occurs, try the actions
specified to resolve your issue. If a file fails export, you might need to try exporting it again. Exporting it
again might require a new job for Snowball Edge.
Files failed export to a Microsoft Windows Server
A file can fail export to a Microsoft Windows Server if it or a related folder is named in a format not
supported by Windows. For example, if your file or folder name has a colon (:) in it, the export fails
because Windows doesn't allow that character in file or folder names.
Action to take
1. Make a list of the names that are causing the error. You can find the names of the files and folders
that failed export in your logs. For more information, see Getting Your Job Completion Report and
Logs in the Console (p. 42).
2. Change the names of the objects in Amazon S3 that are causing the issue to remove or replace the
unsupported characters.
3. If the list of names is prohibitively large, or if the files in the list are too large to transfer over the
internet, create a new export job specifically for those objects.
If the files are small and there isn't a large number of them, copy the renamed objects from Amazon
S3 through the AWS CLI or the AWS Management Console. For more information, see How Do I
Download an Object from an S3 Bucket? in the Amazon Simple Storage Service Console User Guide.
