Ajo p\u00ebrpunon nj\u00eb tabel\u00eb n\u00eb t\u00eb nj\u00ebjt\u00ebn koh\u00eb, rresht pas rreshti.

mysqldump -u root -p --single-transaction --routines --triggers --events --quick production_db > backup.sql\n<\/code><\/pre>\n

2. Ndotja e InnoDB Buffer Pool<\/h3>\n
Kur mysqldump<\/code> lexon \u00e7do rresht t\u00eb \u00e7do tabele, ajo detyron motorin MySQL t\u00eb ngarkoj\u00eb ato t\u00eb dh\u00ebna nga disku n\u00eb InnoDB buffer pool.

Nj\u00eb dump masiv logjik do t\u00eb pastroj\u00eb buffer pool-in, duke nxjerr\u00eb indekset dhe faqet e t\u00eb dh\u00ebnave t\u00eb aksesuar shpesh p\u00ebr t’i b\u00ebr\u00eb vend t\u00eb dh\u00ebnave t\u00eb ftohta q\u00eb po kopjohen. Kjo rezulton n\u00eb nj\u00eb rritje t\u00eb papritur dhe masive t\u00eb I\/O t\u00eb diskut pasi pyetjet e prodhimit detyrohen t\u00eb lexojn\u00eb nga disku, duke \u00e7uar n\u00eb vonesa serioze t\u00eb aplikacionit.<\/p>\n
3. Ky\u00e7et e Metadata-s dhe Konfliktet DDL<\/h3>\n

Nd\u00ebrsa kjo shmang ky\u00e7et e leximit n\u00eb nivel tabele (FLUSH TABLES WITH READ LOCK<\/code>), ajo nuk mbron nga ndryshimet e Gjuh\u00ebs s\u00eb P\u00ebrkufizimit t\u00eb t\u00eb Dh\u00ebnave (DDL). N\u00ebse nj\u00eb komand\u00eb ALTER TABLE<\/code>, DROP TABLE<\/code> ose TRUNCATE TABLE<\/code> ekzekutohet n\u00eb nj\u00eb tabel\u00eb nd\u00ebrsa mysqldump<\/code> \u00ebsht\u00eb duke punuar, kopja rezerv\u00eb do t\u00eb d\u00ebshtoj\u00eb me nj\u00eb gabim table definition has changed, please retry transaction<\/code>.

4. RTO-ja e tmerrshme: Koh\u00ebt e restaurimit<\/h3>\n
D\u00ebshtimi m\u00eb katastrofik i mysqldump<\/code> nuk realizohet gjat\u00eb kopjimit, por gjat\u00eb restaurimit.<\/p>\n
Restaurimi i nj\u00eb dump-i logjik k\u00ebrkon q\u00eb motori MySQL t\u00eb analizoj\u00eb dhe ekzekutoj\u00eb miliona deklarata INSERT<\/code>. P\u00ebr \u00e7do rresht t\u00eb futur, MySQL duhet:
\n* T\u00eb kontrolloj\u00eb kufizimet (\u00c7el\u00ebsat e huaj, \u00c7el\u00ebsat unik\u00eb).
\n* T\u00eb rind\u00ebrtoj\u00eb indekset dyt\u00ebsore n\u00eb koh\u00eb reale.
\n* T\u00eb shkruaj\u00eb n\u00eb regjistrin e rishkrimit (redo log) t\u00eb InnoDB.
\n* T\u00eb pastroj\u00eb n\u00eb binlog (n\u00ebse \u00ebsht\u00eb aktivizuar).<\/p>\n
Restaurimi i nj\u00eb baze t\u00eb dh\u00ebnash prej 1TB nga nj\u00eb dump logjik mund t\u00eb marr\u00eb disa dit\u00eb. N\u00ebse biznesi juaj ka nj\u00eb RTO prej 4 or\u00ebsh, mysqldump<\/code> garanton q\u00eb ju do t\u00eb d\u00ebshtoni n\u00eb Marr\u00ebveshjen tuaj t\u00eb Nivelit t\u00eb Sh\u00ebrbimit (SLA).<\/p>\n
Alternativa t\u00eb nivelit t\u00eb nd\u00ebrmarrjes: Kalimi te kopjet rezerv\u00eb fizike<\/h2>\n
P\u00ebr t\u00eb arritur kopje rezerv\u00eb dhe restaurime t\u00eb shpejta p\u00ebr grupe t\u00eb m\u00ebdha t\u00eb t\u00eb dh\u00ebnave, duhet t\u00eb braktisni kopjet rezerv\u00eb logjike n\u00eb favor t\u00eb kopjeve rezerv\u00eb fizike<\/strong>.<\/p>\n
Kopjet rezerv\u00eb fizike anashkalojn\u00eb plot\u00ebsisht motorin e ekzekutimit SQL t\u00eb MySQL. N\u00eb vend t\u00eb k\u00ebsaj, ato kopjojn\u00eb skedar\u00ebt binar\u00eb themelor\u00eb t\u00eb t\u00eb dh\u00ebnave (skedar\u00ebt .ibd<\/code>, redo logs dhe undo logs) direkt nga sistemi i skedar\u00ebve. P\u00ebr shkak se ato thjesht kopjojn\u00eb skedar\u00eb, ato mund t\u00eb operojn\u00eb me shpejt\u00ebsin\u00eb maksimale t\u00eb leximit\/shkrimit sekuencial t\u00eb pajisjeve tuaja t\u00eb ruajtjes dhe mund t\u00eb paralelohen shum\u00eb.<\/p>\n
Percona XtraBackup: Standardi i Industris\u00eb<\/h3>\n
P\u00ebr motor\u00ebt InnoDB dhe XtraDB, Percona XtraBackup<\/strong> \u00ebsht\u00eb mjeti kryesor i kopjimit fizik me burim t\u00eb hapur. Ai kryen kopje rezerv\u00eb t\u00eb nxehta, pa bllokim, t\u00eb bazave t\u00eb t\u00eb dh\u00ebnave MySQL.<\/p>\n
Si funksionon XtraBackup<\/h4>\n

  1. Kopjimi i t\u00eb dh\u00ebnave:<\/strong> XtraBackup fillon kopjimin e skedar\u00ebve t\u00eb t\u00eb dh\u00ebnave InnoDB (.ibd<\/code>).<\/li>\n

XtraBackup krijon nj\u00eb fije sfondi q\u00eb monitoron dhe kopjon regjistrin e rishkrimit t\u00eb InnoDB (ib_logfile0<\/code>, etj.) p\u00ebr \u00e7do transaksion q\u00eb ndodh gjat\u00eb dritares s\u00eb kopjimit.<\/li>\n

    Hapi 1: Transmetimi i kopjes rezerv\u00eb<\/h3>\n
    Shkrimi i nj\u00eb kopjeje rezerv\u00eb masive n\u00eb diskun lokal shpesh shkakton probleme me kapacitetin. Praktika m\u00eb e mir\u00eb dikton transmetimin e kopjes rezerv\u00eb direkt n\u00eb nj\u00eb format arkive, komprimimin e tij dhe d\u00ebrgimin n\u00eb nj\u00eb zon\u00eb stazhimi ose direkt n\u00eb nj\u00eb platform\u00eb kopjimi rezerv\u00eb.<\/p>\n
