Amazon S3 Bucket name restrictions

Bucket name restrictions for Amazon S3

SPECIAL UPDATE: With the new Amazon configuration for IAS users, NovaBACKUP software is no longer capable of creating a bucket name, the bucket must *first* be configured via the Amazon AWS site, S3 explorer or something similar.  If you are located in the United States then choose "US Standard" for the Region choice when creating the bucket.  We have recently identified that if the bucket region choice is set to Oregon or some other non-"US Standard" choices it may not work to be able to back up to that bucket.

When creating the bucket on the Amazon AWS site it will tell you if the name already exists or if it does not meet the current in place requirements and you will have the choice of choosing the Region.  If the Region choice is set to Oregon our software will probably fail to perform the backup so be careful when selecting the Region during bucket name creation in Amazon AWS. You can access the Amazon AWS site at the following web address:

Note: Please make sure that your Windows Time is set to have daylight savings checked in windows explorer and verify the time is correct.  If this is not checked you will not be able to establish a connection properly within bucket explorer.

Why do some of my requests randomly fail with a 403 Forbidden?

Check the system clock and time zone settings on the offending machine.  Amazon s3 requires all machines making requests be within 15 minutes of an Amazon S3 webserver's clock.  Setting up your machines to sync their times with a NTP server in addition to making sure they are patched for the recent Day Light Savings changes should resolve this issue.

The response from Amazon S3 will contain the following:

    -HTTP Status Code: 403 Forbidden
    -Error Code: RequestTimeToo-Skewed
    -Description: The difference between the request time and the server"s time is too large.
