Zaxira nusxa — alohida, bir martalik servis

qiyin

Zaxira nusxa olish — bir marta ishlab tugaydigan vazifa. always uni tugashi bilan qayta ishga tushiradi. Bundan tashqari u bazadan oldin ishga tushib, connection refused bilan yiqilyapti.

backup uchun restart: "no" qo'ying.
U db sog'lom bo'lgunicha kutsin.
Nusxalar backups nomli volume'da /backups da saqlansin.
backup postgres image'ida qolsin — pg_dump shu yerda.
