Hard drives are cheap. Get an mSATA drive and USB drive enclosure and
every design directory you ever had can be fully backed up onto a device
which reads as fast as your HD subsystems do and will for a long time to
come.

Easy greasy Slap-it-in-and-go-soeasy.

Readonly backups are very comforting if you ever have a ransomware
infection.

The boot up under a Linux live distro, and make the file system on the
mSATA ext4. Done.

I use DVD+Rs and have never had a serious problem with them.


They degrade. Period. That rules them out for me.

Well, you do have to refresh your backups on any medium, including HDDs.
Taiyo Yuden discs have been very reliable for me for about 15 years
now. I wouldn't guarantee that a HDD sitting on a shelf would start up
reliably at that age.

Also nowadays I never attach any remote drive to my filesystem.


You are talking about Windows vulnerabilities, not file system
vulnerabilities. Get a decent OS and your problems go away.

Not true. Synology uses a Linux distro, and there's a dedicated
ransomware version (SynoLocker) aimed at them.

Rsync
and git all the way. Inconvenient, but reduces the attack surface by a lot.


Live boot discs mean ZERO vulnerability.

Not against APTs--they can reflash your hard drive and/ or BIOS, and
operate from there. The ATA command set includes "load microcode", so
it doesn't even need that much hacking.

And even a live CD doesn't help once your disc has been encrypted--it
just makes it impossible to recover.

In short, yes. The Phi cores themselves are mostly x86-compatible,

I've seen.

OTOH, they support OpenCL wery well, so any GPU-aware program

CD's are not a very reliable archival tool. You might look at updating your optical drive to a 25 gigabyte M disc drive.

warning , I have not used a mdisc. And the media does not seem to be in stores.

Supposedly the brand matters a great deal. And if you're using DVDs, use DVR+R. Discussion here:

http://adterrasperaspera.com/blog/2006/10/30/how-to-choose-cddvd-archival-media/

I have found that brand matters a lot for double layer DVDs (DVD+R DL 8.5 GB). The only brand I have found that is reliable is Verbatim.

I never had too many brand related issues with CD-R or single layer DVD.

The likelihood that you'll lose your data from a relaxation of the
original write session (hint, it is NOT "a burn") is far higher than
some stray gamma particle causing an SSD to lose what was written to it.

That is one 'fund' I'll trust forever by comparison, baby

Optical discs which were stamped by a glass master at a factory are
reliable. The crap consumers "burn" are absolutely not (burned or
reliable). The "pits" are mere slight impingements in a plastic layer
made at a very high speed which relax over time or with elevated
temperatures.

Making backups is one thing but organising the media in a sensible way is a
cumbersome task.

Don't bother "organizing"! I'm moving all my "bulk" archives onto external
drives (so they can be easily/quickly moved without having to worry about
building a "compatible" machine to read them WHEN something goes south)
and loosely "mirroring" them -- with the mirrors being <wherever> is
convenient.

Then, logging the contents of each rive in a relational database -- along
with applicable metadata (e.g., MD5's of each file, size, etc.). So,
I can query the database *without* having any drives spinning -- to
locate a file of interest.

Once located, I can spin up the necessary drive(s) and retrieve the file(s).

At the same time, a job systematically walks each filesystem WHEN the
drive is on-line and reverifies the MD5's of each file against the
MD5 stored in the database. So, if a file is in jeopardy (yields
read errors or a bad MD5), I know *then* to hunt down the mirror
copy and create a new backup.

Allowing the "verification" job to be interrupted (e.g., when the drive
is spun down) and *resumed* (in place) means I don't have to leave a box
up for hours while I verify its entire contents.

[At the same time, logging that task's progress (in the database) lets me
know when portions of each medium have been "ignored" for too long...]

You don't want to have them all mounted to a filesystem, though, because
ransomware is spreading like a plague.

You can access the data via a variety of protocols that are less accessible
than a nominally mounted filesystem (assume the host that has them mounted
is "secure"). E.g., FTP, RSYNC, HTTP, etc.

It's not just ransomware. When a disk is spinning and mounted, its
contents can be altered (when its on a shelf, they can't -- shy of
an EMP).

So, if the OS acts up (or the firmware on the drive), your data is at risk.

One reason I don't like COTS RAID arrays is there are still "shared components"
involved for "both" copies of your data: power supplies, CPU's, firmware,
memory, etc.

Decades ago, I had a ~dozen (bare) SCSI drives that I kept as a "cold"
archive; two copies of everything. When I needed a file from the archive,
I'd install a drive in an external SCSI enclosure, cable to the system in
question and then mount(8) the filesystem present on the drive. Copy the
file(s) I needed, then spin down the external drive and put it back on
the shelf.

One day, I installed one, mounted it -- and watched it FAIL in a big way.
My initial assumption was that the *drive* had failed: "(sigh) $1K down
the drain!" So, I pulled the "bad" drive and mounted the mirror copy.
And watched it suffer the same fate! "Hmmm... what are the chances of
TWO drives failing within minutes of each other??"

Turns out, the OS had an "issue" in the driver for the SCSI HBA with
that particular make/model drive -- something that didn't quite work
right (these are formally called "QUIRKS" by the code). Until the
issue had been identified, any drives of that type would suffer the
same fate!

I.e., had both been mounted at the same time, both would have died at the
same time as the problem lie in the OS/driver/HBA/disk combination.
Had all ~dozen of them been spinning in a shelf, I'd be looking at
an order of magnitude higher loss!

In this case, the problem manifested quickly and in a very obvious way;
had the QUIRK been more subtle, it could have been less obvious and not
discovered until a later date -- AFTER I had assumed that the retrieved
file was intact!

This taught me the value of having backups on other forms of media
(I recovered the contents of the drive and its mirror from a third
copy on MO media) *and* the value of having drives with R/O strapping
options! (i.e., try as it may, the OS *can't* alter the contents!)

Things break (aka "Shit Happens") so expecting *anything* and EVERYTHING
to work reliably at all times is a Rx for disappointment!

They are provided you keep them cool, dry and in the dark. I am always a
little nervous of DVDs for high value stuff - I prefer to keep important
files on at least two independent media types.

It is scary seeing what happens to ones used as coasters left outside in
the sunshine. Even a sunny windowsill will degrade lesser brands
(especially if they forgot the UV protection to save money).

I wouldn't guarantee that a HDD sitting on a shelf would start up

Which is why you must not shelve hard drives. I choose to have all my
data online on multiple hard drives. That way I have health monitoring
of the media.
I found out I lost little bits of data by storing it on CDs or hard
drives because I misplaced them or never cared to restore when changing
computers. Making backups is one thing but organising the media in a
sensible way is a cumbersome task.

You don't want to have them all mounted to a filesystem, though, because
ransomware is spreading like a plague.

There is an old-school barrier to malware and ransomware - tape backup.

The reason tape is resistant is because it does not have a file system
on it, and cannot be accessed randomly.

So one recovery dodge if one has a infected disk is to back all desired
files up onto tape, reformat the disk, install a brand new OS image,
and then restore the files.

This will not help if the files were encrypted by ransomware.
