of being transferred as incomplete for their transfer status.
Doing this for import jobs helps ensure that your content can be imported into AWS without issue.
This command might take some time to complete, and might appear to be stuck from time to time.
This effect is common when there are lots of files, and even more so when files are nested within many
subfolders. We recommend that you run this command with the verbose option.

Using the Verbose Option
Whenever you execute a Snowball client command, you can use the verbose option for additional
information. This additional information is printed to the terminal while the command is running.
Using the verbose option helps you to better understand what each command is doing. It also helps
you troubleshoot issues you might encounter with the Snowball client.
The verbose option is off by default. You can turn it on by specifying the option while running a
command, as in the following examples.
snowball -v cp /Logs/April/logs1.csv s3://MyBucket/Logs/April/logs1.csv
snowball --verbose ls s3://MyBucket/Logs/April/

batch:
• By default, files that are 1 MB or smaller are included in batches. You can
change this setting by specifying the --batchFileSizeInKBLimit

range from 100 KB to 1 MB. Files that are larger than the specified
maximum file size are transferred to the Snowball as individual files and
not included in any batches.
