Questions on backing up to S3 Glacier Deep Archive. (lemmy.world)

Hi everyone. I was considering backup options to Glacier Deep Archive, and wanted to know:

Which software do you use to encrypt client-side, obfuscate, compress and deduplicate the data before you send it to S3?
What is the difference between Restore Requests (bulk) and Outbound data transfer and which one will I be using when I want to pull my data from AWS?

I'll be storing approximately 8TB or so of data, which is why I was looking at inexpensive ways to back it up other than buying an HDD outright.

Thanks!

I don't encrypt before I push to S3. Probably bad practice on my part. I just rely on AWS encryption to secure my data. My backups are low-risk (imo). That said, I lock down the bucket so that only my account can access the objects. Compression I use tar cjf (bzip). Protip: Once the tar file is made, run tar ljf $archiveFile > archiveFile-ls.txt and store the resulting file along with the tar file in standard storage. That way you know what is in the archive.
Both. Restore Requests is to copy the data out from Glacier into Standard storage. Note that I said copy. When you perform a restore, your original object stays in glacier and AWS creates a copy to somewhere in S3 that you specify. Once the restore is complete, you can then download the copied object like any S3 object, triggering the Outbound data transfer fee.

Thanks, I'll keep that in mind. I'd encrypt everything client-side since I don't want anyone to know what I'm storing; including the Cloud provider.
