Как мы устали настраивать Crontab и сделали свой cron-manager

В какой-то момент cron-заданий становится много, появляются сложные зависимости между скриптами, когда результат выполнение одного важен для начала работы другого. Балансировать такую историю доводится сис.админу, DevOps'у или разработчику. С этого и начинается наш рассказ.

Selfhosting is nice, and it comes with a price to pay.

For me ? It's time, and I have plenty to give away, given that's my passion.

For my SO ? The unbearable noise of rattling disk needles to write on their very precious platters (especially now, thank you AI bullcrap)

The solution ? A nice cron-based compromise, and I feel like someone could get inspired by this :)

I recently had to do a complete wipe and re-install of my #wpsd #hamradio #hotspot.
Most of the settings were retained by wpsd's backup/restore functions, but my #crontab had to be recreated from scratch.

Luckily I had blogged some of it last year:

Sometimes the only emails I see for days are the daily rsnapshot crontab output emails.

I'm totally ok with this.

In fact, this is preferred.

Yeah meine zweite Festplatte ist heute angekommen !

/dev/sdb 983379700 400782140 5325 43% /mnt/data

/dev/sdc1 983378676 307661060 6256 33% /mnt/data2

Jetzt nur noch mit einem #rsync job täglich #crontab alles von einer Platte auf die andere Platte schaufeln und ich habe wenigstens schonmal ein bisschen #Ausfallsicherheit #backup #Datensicherung für meinen #HomeServer realisiert.

Parallel mache mit "duplicati" ein verschlüsseltes Backup des Betriebssystems in mein #ondrive da habe ich noch 1 TB, warum nicht nutzen wenn man es eh schon hat.
