mysqldump -u root -p --single-transaction --routines --triggers --events --quick production_db > backup.sql\n<\/code><\/pre>\n
Cuireann an bhratach --quick<\/code> iallach ar mysqldump<\/code> sraitheanna a aisghabh\u00e1il ceann ar cheann seachas an t\u00e1bla ioml\u00e1n a mhaol\u00e1n\u00fa sa chuimhne, rud a choscann earr\u00e1id\u00ed As Cuimhne (OOM) ar thaobh an chliaint.

2. Truailli\u00fa Linn Maol\u00e1n InnoDB<\/h3>\n
Nuair a l\u00e9ann mysqldump<\/code> gach sraith de gach t\u00e1bla, cuireann s\u00e9 iallach ar an inneall MySQL na sonra\u00ed sin a lucht\u00fa \u00f3n diosca isteach sa linn maol\u00e1n InnoDB.

Teasta\u00edonn \u00f3n inneall MySQL na milli\u00fain r\u00e1iteas INSERT<\/code> a phars\u00e1il agus a fhorghn\u00edomh\u00fa chun dump\u00e1il loighci\u00fail a athch\u00f3iri\u00fa. Do gach sraith a chuirtear isteach, n\u00ed m\u00f3r do MySQL:
\n* Srianta a sheice\u00e1il (Eochracha Eachtracha, Eochracha Uath\u00fala).
\n* Inn\u00e9acsanna t\u00e1naisteacha a at\u00f3g\u00e1il ar an eitilt.
\n* Scr\u00edobh chuig an loga redo InnoDB.
\n* Sruthl\u00fa chuig an binlog (m\u00e1 t\u00e1 s\u00e9 cumasaithe).<\/p>\n
Is f\u00e9idir go dt\u00f3gfaidh s\u00e9 roinnt laethanta bunachar sonra\u00ed 1TB a athch\u00f3iri\u00fa \u00f3 dhump\u00e1il loighci\u00fail. M\u00e1 t\u00e1 RTO de 4 uair an chloig ag do ghn\u00f3, r\u00e1tha\u00edonn mysqldump<\/code> go dteipfidh ort do Chomhaont\u00fa Leibh\u00e9al Seirbh\u00edse (SLA) a chomhl\u00edonadh.<\/p>\n
Roghanna Eile de Ghr\u00e1d Fiontair: Ag Bogadh go C\u00faltaca\u00ed Fisici\u00fala<\/h2>\n

Seachna\u00edonn c\u00faltaca\u00ed fisici\u00fala inneall forghn\u00edomhaithe SQL MySQL go hioml\u00e1n. Ina \u00e1it sin, c\u00f3ipe\u00e1lann siad na comhaid sonra\u00ed d\u00e9n\u00e1rtha bun\u00fasacha (na comhaid .ibd<\/code>, loga\u00ed redo, agus loga\u00ed undo) go d\u00edreach \u00f3n gc\u00f3ras comhad. Toisc nach bhfuil siad ach ag c\u00f3ipe\u00e1il comhad, is f\u00e9idir leo oibri\u00fa ag an luas l\u00e9itheoireachta\/scr\u00edofa seicheamhach uasta de do chrua-earra\u00ed st\u00f3r\u00e1la agus is f\u00e9idir iad a chomhthreomhar\u00fa go m\u00f3r.<\/p>\n
Percona XtraBackup: Caighde\u00e1n an Tionscail<\/h3>\n
Maidir le hinnill InnoDB agus XtraDB, is \u00e9 Percona XtraBackup<\/strong> an pr\u00edomhuirlis c\u00faltaca fisici\u00fail foinse oscailte. D\u00e9anann s\u00e9 c\u00faltaca\u00ed te, neamh-bhacacha de bhunachair shonra\u00ed MySQL.<\/p>\n
