Kā veikt backup no datubāzes, bez valodas cache saturu

[krisp]

Valodas kešatmiņas var izraisīt datu bāzi līdz 50 reizes lielāks. Nav nepieciešams rezerves šie kešatmiņas, jo viņus nomaina ik pēc 14 dienām anyway. Lūk, kā dublēt datu bāzi kur kešatmiņā tabulās ir pietvīkusi (tukšs) Backup (testēts uz Linux Centos): Batchjob: mysqldump -u username - ppassword databasename | python dump.py > dump.sql, kur šādu python skriptu ar nosaukumu dump.py tiek izmantots:

Atcerieties, lai palaistu: chmod + x / root / dump.py no saknes (vienu reizi tikai pirms braukšanas partijas darba pirmo reizi)

Cita iespējama (nepārbaudītu) vairāk vienkāršs risinājums: mysqldump-u lietotājvārds-ppassword databasename | grep-P-v "INSERT INTO (` table1 `|` table2 `)"> dump.sql

(Atcerieties, lai izmantotu `un nevis")

[vBET]

Un daudz vienkāršāk - vienkārši iestatiet, vBET lietošanas ārējo datu bāzē cache
Tas ir konfigurējams un lepojās ar Admin CP (Admin CP -> vBET Cache -> External DB Cache).

Šo ceļu kešatmiņas tabulās būs citā datu bāzē un jūs varat rezerves jūsu forumā, kešatmiņu un bez jebkādu triku
