Restoring Amazon Glacier Data
When using an Amazon cloud storage, you can choose whether to restore any files located in Amazon Glacier using the corresponding option on this wizard page.
In most cases, these files do not need to be restored and we recommend that you leave this option disabled. Otherwise, please be informed that restoring these files can be either too slow (up to several hours), or too expensive.
However, if you still need to restore Amazon Glacier data, you can select the preferred data retrieval mode on the next wizard page by choosing the corresponding option.
See Amazon Glacier Retrieval Rates to learn about the retrieval modes provided by Amazon.
