Certainly that is the case here.  I have 6 "over"subscribed disks
for my vtapes.  For example D1 is a 4 TB drive with 49 100 GB vtapes.
It currently is at 91% capacity.

RE: Amanda really blew up last night.

[Cuttler, Brian R (HEALTH)]

I missed the early part of the discussion. Vtapes?

I had a large zpool I broke up into vtapes, found that if they where too small 
I'd waste space, if I recall because partial dumps were not removed from the 
'tape' to free up the disk, and if they where too large I'd run into a deadlock 
problem when the pool got full.

Yes, to unused capacity on a vtape is still available in the pool.

At this point I've got 2 zpools and a share on an nfs windows server, though at 
some point in the foreseeable future we will decommission the old Solaris boxes 
and decommission the Amanda server that has been backing them up.

Many thanks to the Amanda developers and community, you have all been wonderful 
to work with over the years.
I don’t know when my last Amanda server will shut down, but likely before I 
retire, still several years off.

I keep reading that there is less wasted space with tapes.   Just because you
allocate X space for each tape,  I believe they only use up the space that’s
actually used.
I does use up another number in your vtape roster, but those seem to me
to be free - just increase your vtape  count and number a few more.

Odd about the holding disk trash preventing further backups.
I find months old stuff in my holding disk, and only clear it out
occasionally when the mood arises.

With vtapes this is true. I keep track of overall drive usage with df, so 
that 2T drive hovers at about 80%, but is falling about 1% a run because 
one of the machines onboard video died and its dle's are commented out 
ATM. I have a couple boxes of old i5 dells optiplexes on a truck from 
pcliquidaters that should fix that if I don't fall over first. S/B here 
about Wednesday. ;-) Blank 250G hd's in them, junk drives I expect but I 
have more of that 240Gig SSD waiting on them. So they will get that same 
240G SSD installed to put LinuxCNC and a debian buster base on them.

I'm beatingthe hell out of SSD's on one of my rpi4b's, moved everything 
like swap off the 64G u-sd, and am running the pi as a buildbot, making 
a new set of debs out of linuxcnc from github, master branch quite a few 
times a week. After changing the name on the usb3 to sata adapter cable 
last spring, no problems since.  Obviously I'm pleased. :-)

I may have an autoflush in my config someplace. And that seems to be 
broken, so I have to clean house before the next run or it somehow mucks 
it up. Not to mention the constat flushing uses about 1% of the big 
drive for everytime it tries.

The holding disk is an SSD of 240G. Swapping it in for the spinning rust 
1T I was using, cut the backup time in half!  I wish I could afford to 
replace the spinning rust, all of it, with SSD's. I could use more of 
the 240's and will, everyplace but this machine. It has around 450G used 
ATM on another 2T.

Take care and stay well Deb. And from what I've read, the mRNA vaccine 
(Phizer,Moderna) is deadly after the 2nd shot, I suspect by plan. 
Exposed to the Wuhan flu after the 2nd shot, your immune system is 
primed to kill you from organ failure. Since Bill Gates paid for that 
vaccine, on purpose would not surprise me.  Load up your daily 
pilltainer with A,C,D bone food, selenium, resveratrol, and in my case 
since I'm a type II diabetic taking metformin by the gram a meal, lots 
and lots of B12.  If your urine isn't yellow, you aren't getting enough. 
B12 is water soluble so you can't OD on it. It just flushes on thru the 
kidneys. I value my friends or I wouldn't be on this soap box about 
skipping the vaccine until we get a non-mRNA version.
