We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

How can I best secure my data in my current set up? (alien.top)

Hi folks,

I've finally set up a proper homelab after years of running a simple *arr and jellyfin set up from a pi.

My setup is as follows:

Sff PC running proxmox on a 258gb ssd for the OS.

I have 1x windows vm which I've done a USB pass through for a yottamaster 5 Bay hardware raid enclosure that has 5x 8tb disks in raid 5.

I have 1x 8tb external drive that has a "copy" of 7.1tb of media that is at my friend's house that is from a month ago.

Now, what is my best way forward?

The raid array only has around 8tb of disk space used. I have signed up for backblaze but as I'm on starlink, this will take a few months to backup everything. I am keenly aware that raid is not a backup and want to make sure I can take care of things as my media collection grows.

Can I compress my media to back it up to a separate drive?

I'm aware of 3-2-1 only by name but not sure what is the best way to proceed in my current circumstances.

Can I compress my media to back it up to a separate drive?

Yes and no.

Yes : You can compress it but the quality will get worse

No : You can compress it without quality loss but you're going to save less than 3%

I'm aware of 3-2-1 only by name but not sure what is the best way to proceed in my current circumstances.

If you want 321 then it might be easier setting up another RPI at the friends house with the backup disk since the majority of data is already on there. Then you can upload to backblaze at your leisure

My concern is as the media (now at 8tb and growing) has surpassed a single disk, will I get away with a second nas with another raid 5 array?

Get another local machine (NAS and etc) and use it as repository for your backups. Other option is simply to get external drive and back everything up to it.

So essentially a nuc and another NAS? would it matter if that NAS was also in raid 5?
