Cloud Backup

[Ghiora Drori]

Hi,
Please read the doc's regarding S3 and Glacier again.
The best way is to backup Linux under Amazon is  to S3. This way you have
immediate access to the recently backed up stuff.
Once the backups are in S3 you can tell Amazon to move it to Glacier  based
on  the names of the files in S3 and* time constraints; *lets say after two
weeks when it becomes less likely you will need it.
Using the S3 Amazon console, you can also specify when to delete the
backups from glacier automatically a very nice feature.
The cost in glacier is very low.
You only pay high fees for restoring from glacier to S3 (From where you can
easily recover to Linux) if you break the rules. Read the rules below:

 https://aws.amazon.com/glacier/pricing
Quote "Glacier is designed with the expectation that retrievals are
infrequent and unusual, and data will be stored for extended periods of
time. You can retrieve up to 5% of your average monthly storage (pro-rated
daily) for free each month. If you choose to retrieve more than this amount
of data in a month, you are charged a retrieval fee starting at $0.01 per
gigabyte. Learn more. In addition, there is a pro-rated charge of $0.03 per
gigabyte for items deleted prior to 90 days."


There is an article by some one who has comprehension problems on the
Internet saying it will cost a fortune to restore, and people seem to be
quoting it a lot.
I have done restores and it is simply not so.
I backup a few 100GB's this way every night. I have done restorations.

As to reliability: (This is effectively a contract):
https://aws.amazon.com/glacier/#highlights
Quote: "Amazon Glacier is designed to provide average annual durability of
99.999999999% "
If this is not good enough for you too bad.

( I do not work for Amazon)

Thanks Ghiora
