Multi-level Incremental Azure Backups?

I've got a TS-469L NAS that's talking to Azure and incrementally backing up every night without issue. However, I'd like to enable multi-level incremental backups - so if a file is edited on a Tuesday, saved, and then on Thursday we discover that the edit was bad and we need the original copy of the file back, we can go back to Monday night's backup to pull the file back out. Is this possible? If not, is my only solution to set up a different job for every day of the week? It seems like that would give me a week of backups to choose from, but at the cost of taking up 7x as much cloud storage. Basically, I'm trying to guard against something like CryptoLocker coming in, encrypting our files, and then having our good backup overwritten with encrypted files and having no way to get the good files back.

Hi, the current design always keep the latest version of your data in the cloud. The feature you need seems to be keeping multiple versions in the cloud. Using multiple backup jobs is a feasible solution for now. We will include your input when planning for the next major release.

Paul, that is excellent news - I think that a multilevel incremental backup would be a fantastic feature for a future release. As for now, we'll make do with multiple backup jobs. Thanks!

Just to comment on this post, its now a while down the line and the multi level redundancy option is still not available.
It would be good to have the option available when creating the backup job to Azure, to choose how many versions of the same file is kept or adopt the GFS (Grandfather, Father, Son) principle.
Any ideas on when and if this feature will be available for Azure Backup?

I am also wondering if there is an ETA for multilevel redundancy. Is there a chance we will see a new version that includes this option soon?

Cheers, Mark

I'd like to add my voice for this functionality too.

Actually, having the Azure app do blob snapshots is probably the best way of doing it. According to the Azure team, snapshots can only be managed through code, so that means the app will have to manage them. Thoughts?

Just adding to this, the option is still not available in the latest builds. Sigh........ and don't think it will be sadly.
I also hate to be the barer of bad news, but Synology have already done this.

Due to the Azure storage limitations on multi-versioning, QNAP do flat file backup to the Storage Blog, so you can log in via the Azure Storage Explorer and recover files directly from the cloud. yay great..... but no multiple versions unless you have multiple containers for different backup jobs.....

Synology however have created their own file system / datbase for storing this data in Azure, so you have a database which keeps track of the location of the files, thus making Synology have the ability to recover from previous backups, giving the ability of file versioning.

QNAP would have to design a Database / File System to keep track of changed files when using Azure Storage accounts, so this means you don't have the simple task of flat file data in one blob.

QNAP would have to redesign the Azure Storage App and the way it backs up data.

That probably why no one from QNAP has responded with an ETA on this in 3 years.....
