Backup Strategy using QNAP

Post by gunnerman » Tue Oct 22, 2019 1:43 am

Hello,

I am a little concerned about our current backup strategy using the QNAP NAS. I am worried we may be using up more storage than need be.

Right now we have 2 TS-463U with identical config. 4 x 4Tb drives in RAID 10. One is used as a primary and the other as a backup. We have 4 shared folders on on the primary which I backup daily using RTRR to the secondary NAS using version management keeping versions of various times depending on the share. I also take weekly snapshots on the primary and keep them for 3 weeks.

As well as this I also backup the entire NAS to Azure storage once a month.

What I am worried about, is these are all replication jobs. There does not seem to be an automated "backup" that will create a new backup in a folder on a schedule. What I mean is, if I have a backup storage space on remote nas, call it "Backups", in that folder when a backup job runs it should create a new folder, call it backup_<folder_name>_<current_date>. That way the backup runs independent of other backups in that folder. Right now, the only way to do this is with Snapshot replication? I don't have the storage to replicate snapshots.

To combat this, I keep many versions of files, and duplicate jobs that run at separate times. Thus, in case I am hit with corruption or ransomware, it reduces the risk of replicating the corruption or ransomware to the backup. Unfortunately, versioned backups are kind of hard to deal with. Lots of folders with different versions.

I would love if there was the ability to make simple, real, backups. It would be nice to keep versions around for when users screw up and then a few simple backups around following 3-2-1 for easy restore and protection. Relying on file versions just seems like another area of complexity on something that should be very easy and very sure. I know I could do this easily enough with a cron job and a few bash scripts but I like to avoid this where possible. Am I missing something in the Backup Station settings?

That's how the Qnap versioning feature works, or at least it did before QuDedup was released in Hybrid Backup Sync 3. I haven't really used QuDedup yet as I like the non-proprietary format of the old versioning.

In Backup Station you can have versioning if you install the versioning app (if that's still available). That app was never released into a stable version (despite the versioning beta app in my experience ran complete stable for more than a year) and therefore I can't really recommend it for production usage.

Backup Station is legacy software today and the backup solution from Qnap going forward is the Hybrid Backup Sync app. HBS did versioning the way you want it in the first two versions but when HBS 3 was released it had the new QuDedup feature moving to a proprietary backup file format (with the advantages and disadvantages that have) and unfortunately QuDedup was made mandatory instead of user configurable. :cry:
RAID have never ever been a replacement for backups. Without backups on a different system (preferably placed at another site), you will eventually lose data!

A non-RAID configuration (including RAID 0, which isn't really RAID) with a backup on a separate media protects your data far better than any RAID-volume without backup.

All data storage consists of both the primary storage and the backups. It's your money and your data, spend the storage budget wisely or pay with your data!

I'm working on it. My plan is:
1. Not using HBS3 for any serious backup. Too many missing files.
TVS-951x 16GB RAM, 2x0,5 TB SSD RAID1, 3x8 TB RAID5
TS-431P2 8GB RAM, 4x 3 TB HGST RAID5
Unraid 8GB RAM, 10x 3TB HGST
