Unfortunately, amanda is truely ancient, for some reason the originator
who first wrote it in the later 70's IIRC sold it nearly 20 years ago to
a commercial outfit called zmanda, who took it more or less commercial,
throwing the amanda named version under the buss. They must have ran out
of money and resold it to another outfit, who has redoubled their effort
to get rid of the free version. One of the things it has not been fixed
to do, is issue a wakeup call, and wait for the clients to get their
stuff in one sock, say 30 seconds to get everything spun up and ready to
take orders, so I'm pretty sure a client that doesn't respond in
milliseconds will be skipped. So basically, amanda needs to be
officially forked since the current owner, Betsol has not made any
contribution to amanda that amounts to an actual update but once in 6 or
7 years now, There's several things it now needs, such as the
wake-on-lan support done right. Python is part of it but python 2 is
still needed. Or a whole new start for something to replace and put it
back squarely in the gplv2 or 3 camp. If there is actually another
capable of diddling the level schedule like amanda does, I'm sure I
could name some of the major users that would jump ship in a week or so
once they became aware of a workalike.
It appears Amanda has a script API for both the client and the server:
https://manpages.debian.org/buster/amanda-common/amanda-scripts.7.en.html
The zmanda wiki has a Script API page, but it is empty (?):
https://wiki.zmanda.com/index.php/Script_API.
For BIOS/UEFI wake-on-lan, it might be possible to write a script that
wakes the clients, to write a script that shuts down the clients, to
configure the Amanda server to run the wake script before backups, and
to configure the Amanda server to run the shutdown script after backups.
For BIOS/UEFI wake at preset day/time, it might be possible to set the
clients to wake before the scheduled backup time, to write a script that
shuts down the clients, and to configure the Amanda server to run the
shutdown script after backups.
