I use my external USB drives for off-site backup, so I use ext4 on top
of an encrypted partition.

Go for ext4.  No reason not to.

I use and recommend ext4. Journaling protects against filesystem 
metadata corruption, which can be caused by an electrical outage or 
system crash. ext3 also has journaling, but I see no reason to not use 
ext4. It is robust, widely deployed, and the default in Debian.


My backups are pigz-compressed tar archives, encrypted with gpg 
symmetric encryption, with a "pigz -0" outer wrapper to add a 32-bit 
checksum wrapper for convenient verification with "gzip -tv" or similar 
without requiring decryption. Archives are written to both external 
local storage and uploaded to cloud storage.


Because I have a small number of large backup files, I make backup 
filesystems to optimise for large files and maximise space: minimal 
journal, no reserved blocks, large file inode ratio, and no support for 
resizing while mounted. I also disable mount count and interval checking:


mkfs.ext4 -J size=4 -m 0 -T largefile4 -O "^resize_inode" /dev/sdb1
tune2fs -c 0 -i 0 -L Backup /dev/sdb1

I have this line in /etc/fstab:

LABEL=Backup /media/backup ext4 noatime,noauto,user,errors=remount-ro 0 0

I use ext4.   The advantage is journaling, which as I understand it 
reduces the chance of loss in case of power failure or the like. If 
you're using rsync, it will correct any prior bad copies (I think) at 
the next run.


On the basis that 1 back-up is better than none, can you cope with 2 
external devices?   As somebody else said in another topic, (approx) as 
long as you have a well tested spare lying around for when the main 
target fails.   Somebody put it more like this many years ago: There are 
2 kinds of drives around; those that have failed, and those that are 
going to fail.  Thankfully failure is getting rarer.

Only in places that need vast amounts of data stored for a very long
time with restores being rare. Restoration is slow with tapes. Even
a low end LTO drive will set you back thousands of £/$/€.

Most consumers and even most businesses will find it more cost
effective and flexible to backup to HDDs and storage clouds.

No, not "it" logged you out. When you say "exec", you say "replace
the currently running process by that other". When  "that other"
terminates... it's done. So it won't come back to your shell. It's
gone. Basically, with "exec" you logged you out yourself, kind of.

 The only thing that I have "discovered" is that for whatever reason
that keyboard doesn't plug directly to one and only one of the USB
ports (which I had used before just fine), but if connected through a
USB hub it works just fine. So I wonder what could be going on, or

So don't do that.  Test it with ./run instead, like I said.

Because you haven't started the service yet.  That will be created
once daemontools runs it for the first time.

Because you haven't started the service yet.

You need to create the symlink to start the service.

This is all correct, but in addition:

svc -d /service/dnscache
  brings it down via the supervisor, similar to the action of
"service dnscache stop" or "/etc/init.d/dnscache stop"

svc -u /service/dnscache
  should start running it again

All of this clashes with manual invocation of ./run, so that has
to be killed before daemontools can take over.

You can execute the "./run" script by hand for testing purposes, to
make sure you've written it correctly, but that's not how daemontools
will run it.  If your test is successful, you should Ctrl-C (or otherwise
terminate) the ./run script that you ran manually.  Make sure it dies.

You tell daemontools to run the service by creating a symbolic link
from the /service directory to the directory where the run script
lives.

For example:

unicorn:~$ ls -l /service
total 0
lrwxrwxrwx 1 root root 13 Jan 12  2018 dnscache -> /etc/dnscache/
lrwxrwxrwx 1 root root 39 Jan 12  2018 qmail-deliverabled -> 
/var/qmail/supervise/qmail-deliverabled/
lrwxrwxrwx 1 root root 31 Jan 12  2018 qmail-send -> 
/var/qmail/supervise/qmail-send/
lrwxrwxrwx 1 root root 28 Jan 12  2018 qpsmtpd -> /var/qmail/supervise/qpsmtpd/

unicorn:~$ ls -l /etc/dnscache/
total 24
drwxr-sr-x 2 root root 4096 Jan 12  2018 env/
drwxr-sr-x 4 root root 4096 Jan 12  2018 log/
drwxr-sr-x 4 root root 4096 Jan 12  2018 root/
-rwxr-xr-x 1 root root  142 Jan 12  2018 run*
-rw--- 1 root root  128 Jan 12  2018 seed

The presence of the symlink /service/dnscache is picked up by svscan,

dns cache for localdomain via djbdns

[Patrick Frank]

Hello,

on a Debian 10 host I created a virtual machine with very basic features
to build a dns cache for my home network with djbdns. I fail to understand
how Daemontools are used properly.

Following the instructions on http://cr.yp.to/djbdns/install.html went okay.
http://cr.yp.to/djbdns/run-cache-x.html at step 5 is where I am stuck.

When I go to /service/dnscache and execute "run" it says "starting" so I
try svstat /service/dnscache which outputs:
"/service/dnscache: unable to open supervise/ok: file does not exist"

Any hints, please?

New tape drives are expensive because they are only sold to
businesses; used tape drives are cheap because no business wants
to buy them.

That said, even a new tape drive is a finicky beast compared to
a spinning disk; anyone operating them should really have a
spare drive, tested, sitting around and waiting for the primary
one to fail.

Yes.

However, my company has switched over to using disk storage for
backups. The time-cost for retrieving a file or a directory is
much lower, and we do that small recovery much more often than
we need to bring back an entire machine. 

Also note that LTO-2 is 200GB per tape, not 600. Tape
manufacturers have an awful habit of pretending that all data is
compressible, and citing a compressed storage amount instead of
the raw storage amount.

Depends on the context you're talking about.

I am given to understand that people do very much still use tape drives
for backup in a server-room / data-center type of context.

However, while I've considered using tapes for backup in my own private
environment, last time I looked the cheapest tape drive with support for
tapes large enough to be reasonable for my hard-drive capacities was
$3000 - and that's just the drive, not the tapes. That rivals - and may
surpass - the build-from-parts cost of my entire computer, which is
already nearly half storage by dollars spent.

It's possible things have changed since then, but I'd be surprised if
tape drives were economical enough to be practical in a non-commercial
environment.

Do people use tape drives for backup ?
I saved data to tape before but I think they were DAT and not very big 
but see that these LTO-2 tapes are 600Gb and not expensive.

Do people use those ?

  a butter knife will work ok too.

  i agree though about the Model M and similar keyboards and
really miss mine.  too bad that that unicomp keyboards won't
work for me (i've broke two of them the past x number of years
and can't figure out how to fix them and since they're not
sturdy enough it isn't worth sending them in for repairs).

  yeah, there can be a bit of a challenge to figure out
some things.

  right now i have two keyboards i took apart to see if 
i could fix them or combine them to get one working keyboard
but as it turns out there is some kind of pressure/ribbon
connection inside that i've screwed up and now both are shot 
for sure.  too bad as i really liked them, but they could 
not hold up to how i used them and broke (all plastic case
is too flexible and eventually the connections inside fail
if you use it unsupported propped across your lap).
