I’ve been attempting to make a backup to Amazon S3 using the Cloud Backup feature. My aim is to do a one off initial backup of everything (currently around 500GB) and have this maintained incrementally thereafter.
Obviously backing up 500GB of data is a fairly time consuming process … I have a reasonable amount of bandwidth but I’d expect this to take about a week to complete. Unfortunately every time I’ve tried this so far the process has stopped with an indeterminate error after a couple of days (the partial transfer to S3 seems to be just fine).
This shouldn’t be more than a minor irritation, because I have the backup mode set to “Incremental”, so I should just be able to restart the backup process and have it pick up from where it left off, right? Sadly not … it appears to restart from the beginning overwriting files which have already been transferred (there have been no local writes in the interim), which makes it seem unlikley that the process will ever complete. Even if it did, I don’t have a lot of confidence that subsequent incrementals wouldn’t just attempt to transfer the whole lot again.
Has anyone else experienced these issues or similar? Does anyone have any success stories, and if so do they have any advice for me?
