I have a SOHO file server with ~1 TB of data. I would like archive
the data by burning it to a series of optical discs organized by time

future, each covering a span of time from the previous last disc to
the then-current time.
I am looking for FOSS software for Unix platforms that goes beyond a
disc burner with multi-volume spanning. The term "archive management
system" comes to mind.
Comments or suggestions?
Take a look at amanda, although the optical is not on my radar because
of the low capacity of a dvd at 4.7gigs. Amanda can use an lvm for
v-disks, which if you want say 60 days back as bare metal recover, would
actually be the contents of 60 directories in that lvm, allowing any
file up to 60 days old to be recovered.
Here, with all my machine on my local network, and before I started with
3d printers which need maybe 30 gigabyte of gcode to drive the printers
to make one complex part, 5 machines backed up for 60 days, was filling
a 1T drive to around 87%. So I bought 2 2T seagates, got buster
installed and everything running smoothly. Installed buster on oe drive,
configure amanda to use the other. 3 or 4 weeks later, both of those
seagates dropped off the sata controller in the night, and I rebuilt
with SSD's and bookworm which has been the disaster you all have been
trying to help me with since, but its not running well enough to be
worth reinventing my amanda setup which just grew since about 1999.
Amanda was developed for use with qic or thereabouts tapes so its prime
directive is to juggle the backup levels to fully fill the tape(s) while
doing a level0 on everything withing the time limit in days between
level0's. It can use a tape library of however many tapes the library
contains. Bring big red wagonloads of cash for those. But I gave up on
tapes 15 years ago, they simply weren't dependable enough, while
spinning rust, never shut down can sit there and spin for 50,000+ hours,
they've done it for me.
The 1T I took out, a cheap 5400 rev barracuda, had just under 70,000
spinning hours on it with maybe 40 power downs on it, when I retired it
cuz it was getting too small, for the 2T that lasted less than a month.
In spinning rust, power downs are the drive killers, so spin them up and
leave them spinning, the heads aren't wearing while they are flying on 3
microns of air between the head and the platter.
Set it up right, and amanda will have your back till the place is a few
inches of ashes. And you can set to cycle the storage drive(s) offsite,
exchanging them weekly or monthly, what ever you're comfortable with.
That adds to the powerdown count however so I never did that.
Thank you for the reply. :-)
