S3 is awesome for backup
Authored by: sreitshamer on Mar 03, '10 07:24:27AM

S3 is great for backup. The objects in your S3 bucket are stored in multiple locations; upload and download is very fast. It's run by a $50B+ public company instead of a startup. Their API works great for backup and restore when combined with great client software.

s3sync is cool but it doesn't have file encryption or versioning, is slow when backing up lots of small files (due to HTTP overhead), doesn't de-duplicate your files, and doesn't get around the S3 file size limit of 5GB (5368709120 bytes, not 4GB as mentioned in another comment).

One thing that's key about Mac backups is preserving all the metadata. As of February 2010, most online backup providers (including Mozy, Backblaze, Carbonite and CrashPlan Central) fail most of the Backup Bouncer tests.

If you'd like backup to S3 for the Mac that's hand crafted specifically for the Mac (and only the Mac), keeps file versions like Time Machine (keeps hourly backups for 24 hours, daily backups for a month and weekly backups up to a storage budget you choose), handles small files very efficiently, does de-duplication, has easy drag-and-drop restore, does file encryption, and has no file size limit, try Arq. It passes all the Backup Bouncer tests.
