I'm not usually an early adopter, but I found the testing results impressive. Any thoughts out there? > Hi, Bryan, I don't know precisely how you are employing the M-Discs, but I've really lost interest in media that multiplies by the hundreds or thousands. I've become a fan of a variety of storage technologies. Currently, I'm experimenting with BackBlaze as my off-site backup solution to complement my two RAID-6 on-site NAS units. BackBlaze will back up one computer for $100 US / year. They specifically state that they don't care how large a drive (or drives) you have in it. I bought a 12 TB drive... I realize that won't scale (or fly) for a professional archive, but they offer professional services as well (for more money). With my small outbound bandwidth of 10 Mb/s, it looks as if it will take 12-14 weeks to complete (I find their estimates wrong based on the history). I started this in mid-April and have backed up 99.4 % of my files (767,033 of 771,237) BUT have about 47 % (4,167,028 out of 8,892,881 MB) remaining. I have been at it about six weeks, hence my 12 week estimate. It may take a bit longer now that we're home, we may wish to upload other things, so I pause BackBlaze when that happens. They back up the largest files last. Here, I am running four 24/7 computers. --Mail-runs my email and also handles all of the NAS-to-NAS backups (I prefer the flexibility of ViceVersa Pro to RSYNC). --NAS1 "18 TB" of capacity (based on disk sizes)--my main unit --NAS2 "12 TB" of capacity--backs up many things --Support (12 TB HDD)--is the "landing pad" for both the boys' Dropboxes which are selectively backed up to the NAS units and completely backed up to BackBlaze as well as most of the NAS1 content is also copied to this for BackBlaze backup. There is no console on the Support computer--I ONLY remote desktop into it. The Mail machine has a console and is also our image scanning workstation. I use a 3rd party RDP server (Thinstuff) that permits me to log in to the Mail account while a photo account is active at the console. When BackBlaze is full loaded, I will decommission my two older Netgear ReadyNAS units that server as a suitcase off-site backup. Cheers, Richard -- Richard L.
