Re: Backup using i2s3? or other svc?

[Ron Adams <rondadams@xxxxxxxxx>]

Amazon offers an Import/Export service for large transfers where they will
read/write to an external device.
The trick would be getting on or off the iseries as the only device
interfaces they support are USB and eSATA. So, you would have to transfer
the files to a PC, then upload them to the iSeries, or vice versa. The time
would be quicker, but with shipping and then the dual transfers, I'm not
sure how much. Like everything, it just depends on how much data is being
tranferred.
