Backups and Redundancy - Choosing The Right One 

"sloooooww downnnn soooo much" - made my day!

Good to raise awareness, something can happen to your NAS and you can lose all the data. I would not advise to use USB sticks for a backup-strategy as I've seen USB sticks all of a sudden die due to heat (high-speed writing) or merely can not cope with such a specific purpose. I would also recommend, if budget allows for it, to spread your data across multiple NAS. E.g 1x for Plex, 1x photos, 1x backups of machines (TimeMachine etc). And whenever you "out grow" a NAS, it can be repurposed for backups. (although always keep an eye on the age of your HD's, the wear-and-tear)

Some great Info, cleared up some aspects of how some raid levels work. Will help me make better decisions in future backup plans. Thanks

Move from cloud to NAS Now need cloud to backup NAS ...old man shakes his fist at clouds

In Synology, Hyperbackup is a great application. You can schedule this, it runs twice a week to a eSATA connected hard drive. Works amazingly well. All tough I have RAID 10 configuration, but safety first :)

USB media that is not permanently connected is a good protection from things like ransomware.

Great timing! I’m thinking ahead as I am working though my NAS/Network upgrade. My existing NAS is a Drobo. My new NAS is a Synology. Once up and running and all my data is migrated, I plan to use the Drobo as an on-site backup for critical data from my Synology. I’m trying to come up with a backup strategy and happen to catch your video today. There are what appears to be a couple options for backing up NAS to NAS. My question is, will they both work with different NAS manufacturers, Synology to Drobo? I believe my options are Rsync and Snapshot. Will either of these work on both NAS’s? Any other options? TIA

Is there an approach where you can make a backup to a disk/NAS that can be disconnected and moved off site and then store snapshots or incremental backups in the cloud. This could result in lower cloud costs and lower bandwidth issues on the initial backup.

I recently got a DS223 after your suggestion with first one 4TB HDD and later one I added a second 4TB, exactly the same as the first one. Having the first already data on it, how should I have the second *for redudancy*, as it permanently tells me the second dusk is not being used. Pool and volume have already been created. Thanks

Thanks.

I have 20TB of data and getting larger. Therefore cloud is off the cards. Can you make recommendations based on size brackets? Maybe in the comments. Thanks again.

How about snapshots sent to the cloud .... timed at 4am. Plus a monthly backup of changes on a a 2 mirrored disk array 🤔

Woah, woah guys, about to buy my first NAS and thought you just use another bay as backup? Wtf.

Good stuff..keep on going

Snapshots are of course Time Machine on Macs and work well

These snapshots you mention , are they saving changed or new files only. I use a full snapshot once a week.

Would RAID 1 be a backup?
