Basitlik Yan\u0131lsamas\u0131: Klasik DIY Beti\u011fini \u0130ncelemek<\/h2>\n

Tehlikeyi anlamak i\u00e7in \u00f6nce tipik bir DIY yedekleme beti\u011finin anatomisine bakmal\u0131y\u0131z. Bir MySQL veritaban\u0131 i\u00e7in standart bir yakla\u015f\u0131m genellikle \u015funa benzer:<\/p>\n

#!\/bin\/bash\n# Basit DIY MySQL Yedekleme Beti\u011fi\nBACKUP_DIR=\"\/mnt\/backups\"\nDATE=$(date +%F)\nDB_USER=\"admin\"\nDB_PASS=\"SuperSecret123!\"\n\nmysqldump -u $DB_USER -p$DB_PASS my_database | gzip > $BACKUP_DIR\/mydb_$DATE.sql.gz\n\n# 30 g\u00fcnden eski yedekleri sil\nfind $BACKUP_DIR -type f -name \"*.sql.gz\" -mtime +30 -exec rm {} ;\n<\/code><\/pre>\n
\u0130lk bak\u0131\u015fta bu betik amac\u0131na ula\u015f\u0131r: veriyi \u00e7\u0131kar\u0131r, s\u0131k\u0131\u015ft\u0131r\u0131r ve saklama s\u00fcresini y\u00f6netir. Ancak y\u00fczeyin alt\u0131nda, \u00fcretim ortam\u0131nda er ya da ge\u00e7 veri kayb\u0131na yol a\u00e7acak kritik kusurlarla doludur.<\/p>\n
Tehlike 1: Sessiz Hatalar ve Boru (Pipe) Tuza\u011f\u0131<\/h2>\n
DIY betiklerinin en sinsi tehlikelerinden biri sessiz hatad\u0131r. Yukar\u0131daki betikte, mysqldump<\/code> komutu do\u011frudan gzip<\/code>‘e borulan\u0131r (|<\/code>).<\/p>\n
Bash’te bir boru hatt\u0131n\u0131n \u00e7\u0131k\u0131\u015f durumu, boru hatt\u0131ndaki son<\/em> komutun \u00e7\u0131k\u0131\u015f durumudur. Veritaban\u0131 sunucusunun belle\u011fi biterse, ba\u011flant\u0131 koparsa veya dump i\u015flemi s\u0131ras\u0131nda kilitli bir tabloyla kar\u015f\u0131la\u015f\u0131l\u0131rsa, mysqldump<\/code> ba\u015far\u0131s\u0131z olur ve bir hata verir. Ancak gzip<\/code>, ald\u0131\u011f\u0131 k\u0131smi \u00e7\u0131kt\u0131y\u0131 ba\u015far\u0131yla s\u0131k\u0131\u015ft\u0131racak ve 0<\/code> (ba\u015far\u0131l\u0131) durum koduyla \u00e7\u0131kacakt\u0131r.<\/p>\n
Cron i\u015finin \u00e7\u0131k\u0131\u015f kodunu kontrol eden izleme sisteminiz, ba\u015far\u0131l\u0131 bir yedekleme rapor edecektir. Diskte ge\u00e7erli bir .gz<\/code> dosyan\u0131z olacakt\u0131r ancak i\u00e7inde kesilmi\u015f, i\u015fe yaramaz bir SQL dosyas\u0131 bulunacakt\u0131r. Bunu ancak kritik bir geri y\u00fckleme yapmaya \u00e7al\u0131\u015ft\u0131\u011f\u0131n\u0131zda ke\u015ffedeceksiniz.<\/p>\n
Azaltma (ve s\u0131n\u0131rlar\u0131)<\/h3>\n
M\u00fchendisler genellikle Bash’te kat\u0131 hata i\u015flemeyi etkinle\u015ftirerek bunu yamamaya \u00e7al\u0131\u015f\u0131rlar:<\/p>\n
set -e\nset -o pipefail\n<\/code><\/pre>\n
set -o pipefail<\/code>, boru hatt\u0131ndaki herhangi bir<\/em> komut ba\u015far\u0131s\u0131z olursa beti\u011fin ba\u015far\u0131s\u0131z olmas\u0131n\u0131 sa\u011flasa da, yine de beti\u011fin etraf\u0131nda sa\u011flam uyar\u0131, g\u00fcnl\u00fck kayd\u0131 ve yeniden deneme mekanizmalar\u0131 olu\u015fturman\u0131z\u0131 gerektirir. Ge\u00e7ici bir a\u011f hatas\u0131 saat 02:00’de bir hataya neden oldu\u011funda, bir DIY beti\u011fi basit\u00e7e durur. Kurumsal platformlar bu ge\u00e7ici hatalar\u0131 ak\u0131ll\u0131, \u00fcstel geri \u00e7ekilme (exponential backoff) yeniden denemeleriyle y\u00f6netir.<\/p>\n
Tehlike 2: Veri Tutarl\u0131l\u0131\u011f\u0131 ve Kilitleme Kabuslar\u0131<\/h2>\n
DIY betikleri b\u00fcy\u00fck \u00f6l\u00e7\u00fcde mant\u0131ksal yedeklemelere (mysqldump<\/code>, pg_dump<\/code>) dayan\u0131r. Mant\u0131ksal yedeklemeler, t\u00fcm tablolarda SELECT<\/code> ifadeleri \u00e7al\u0131\u015ft\u0131rarak verileri \u00e7\u0131kar\u0131r. Y\u00fcksek d\u00fczeyde i\u015flemsel bir \u00fcretim veritaban\u0131nda veriler s\u00fcrekli de\u011fi\u015fir. Bir beti\u011fin 100GB’l\u0131k bir veritaban\u0131n\u0131 dump etmesi 45 dakika s\u00fcrerse, dump’\u0131n ba\u015f\u0131ndaki veriler sonundaki verilerden 45 dakika daha eski olacak ve ACID uyumlulu\u011funu ihlal edecektir.<\/p>\n
MySQL \u0130\u015flemsel Tutarl\u0131l\u0131\u011f\u0131<\/h3>\n
InnoDB kullanarak MySQL’de tutarl\u0131 bir anl\u0131k g\u00f6r\u00fcnt\u00fc (snapshot) elde etmek i\u00e7in belirli bayraklar\u0131 ge\u00e7meniz gerekir:<\/p>\n
mysqldump --single-transaction --quick --routines --events -u user -p db > dump.sql\n<\/code><\/pre>\n
--single-transaction<\/code> bayra\u011f\u0131, yal\u0131t\u0131m seviyesini REPEATABLE READ<\/code> olarak ayarlar ve dump i\u015fleminden \u00f6nce bir i\u015flem ba\u015flat\u0131r. Ancak veritaban\u0131n\u0131z hala eski MyISAM tablolar\u0131 i\u00e7eriyorsa, bu bayrak onlar\u0131n kilitlenmesini \u00f6nlemeyecek ve yedekleme \u00e7al\u0131\u015f\u0131rken \u00fcretim okuma\/yazma trafi\u011fini potansiyel olarak durduracakt\u0131r. Ayr\u0131ca, yedekleme s\u0131ras\u0131nda geli\u015ftiriciler taraf\u0131ndan y\u00fcr\u00fct\u00fclen herhangi bir ALTER TABLE<\/code>, DROP TABLE<\/code> veya RENAME TABLE<\/code> ifadesi REPEATABLE READ<\/code> anl\u0131k g\u00f6r\u00fcnt\u00fcs\u00fcn\u00fc bozacak ve dump’\u0131n ba\u015far\u0131s\u0131z olmas\u0131na neden olacakt\u0131r.<\/p>\n
PostgreSQL ve WAL Ar\u015fivleme<\/h3>\n
PostgreSQL i\u00e7in pg_dump<\/code> tutarl\u0131 mant\u0131ksal yedeklemeler sa\u011flar, ancak yaln\u0131zca mant\u0131ksal yedeklemeler Noktasal Kurtarma (PITR) sa\u011flayamaz. Veritaban\u0131n\u0131z saat 16:00’da \u00e7\u00f6kerse ve son cron beti\u011finiz gece yar\u0131s\u0131 \u00e7al\u0131\u015ft\u0131ysa, 16 saatlik veriyi kaybedersiniz.<\/p>\n
PITR’ye ula\u015fmak, Yazma \u00d6ncesi G\u00fcnl\u00fcklerin (WAL) s\u00fcrekli ar\u015fivlenmesini gerektirir. archive_command<\/code>‘\u0131 g\u00fcvenli bir \u015fekilde i\u015flemek i\u00e7in bir DIY beti\u011fi yazmak olduk\u00e7a zordur.<\/p>\n
# postgresql.conf\nwal_level = replica\narchive_mode = on\narchive_command = 'test ! -f \/mnt\/wal_archive\/%f && cp %p \/mnt\/wal_archive\/%f'\n<\/code><\/pre>\n
Hedef depolama (\/mnt\/wal_archive\/<\/code>) dolarsa veya kullan\u0131lamaz hale gelirse, archive_command<\/code> ba\u015far\u0131s\u0131z olur. PostgreSQL daha sonra birincil disk dolana kadar WAL dosyalar\u0131n\u0131 yerel olarak biriktirir ve bu da tam bir veritaban\u0131 kesintisine neden olur. DIY betikleri, bir kesinti meydana gelmeden \u00f6nce WAL birikimini izlemek ve y\u00f6neticileri uyarmak i\u00e7in gereken telemetriye nadiren sahiptir.<\/p>\n
Tehlike 3: Saklama Ruleti<\/h2>\n
\u0130lk beti\u011fimizdeki saklama komutuna geri bak\u0131n:<\/p>\n
find $BACKUP_DIR -type f -name \"*.sql.gz\" -mtime +30 -exec rm {} ;\n<\/code><\/pre>\n
Bu, ger\u00e7ekle\u015fmeyi bekleyen felaket niteli\u011finde bir veri kayb\u0131 olay\u0131d\u0131r. Bir yap\u0131land\u0131rma de\u011fi\u015fikli\u011finin mysqldump<\/code> kimlik do\u011frulamas\u0131n\u0131 bozdu\u011fu bir senaryo hayal edin. Betik yeni yedekler olu\u015fturamaz, ancak find<\/code> komutu her gece \u00e7al\u0131\u015fmaya devam eder ve 30 g\u00fcnden eski dosyalar\u0131 g\u00f6rev bilinciyle siler.<\/p>\n
30 g\u00fcnl\u00fck sessiz yedekleme ba\u015far\u0131s\u0131zl\u0131\u011f\u0131ndan sonra, find<\/code> komutu kalan son iyi yede\u011finizi de silecektir. Art\u0131k elinizde hi\u00e7 yedek kalmam\u0131\u015ft\u0131r.<\/p>\n
CloudSave gibi kurumsal yedekleme yaz\u0131l\u0131mlar\u0131 durum bilgisi olan (stateful) saklama politikalar\u0131 kullan\u0131r. “30 g\u00fcnden eski yedekleri sil” ile “eski verileri temizlemeden \u00f6nce en az 30 ba\u015far\u0131l\u0131 kurtarma noktas\u0131n\u0131n var oldu\u011fundan emin ol” aras\u0131ndaki fark\u0131 anlar.<\/p>\n
Tehlike 4: G\u00fcvenlik, \u015eifreleme ve Uyumluluk K\u00f6r Noktalar\u0131<\/h2>\n
Fidye yaz\u0131l\u0131m\u0131 ve kat\u0131 uyumluluk \u00e7er\u00e7eveleri (GDPR, HIPAA, SOC 2) \u00e7a\u011f\u0131nda, yedeklemeler birincil hedeftir. DIY betikleri genellikle g\u00fcvenlik en iyi uygulamalar\u0131n\u0131 ihlal eder:<\/p>\n
    \n
  1. Sabit Kodlanm\u0131\u015f Kimlik Bilgileri:<\/strong> Veritaban\u0131 \u015fifrelerini d\u00fcz metin betiklerinde veya cron tan\u0131mlar\u0131nda saklamak b\u00fcy\u00fck bir g\u00fcvenlik riskidir. MySQL’in mysql_config_editor<\/code> veya PostgreSQL’in .pgpass<\/code> dosyas\u0131 gibi ara\u00e7lar bunu hafifletse de, yine de sunucudaki yerel anahtar dosyalar\u0131n\u0131 y\u00f6netmeyi gerektirirler.<\/li>\n
  2. Bekleyen Verinin \u015eifrelenmemesi:<\/strong> Ham SQL’i bir diske d\u00f6kmek, hassas PII\/PHI verilerini a\u00e7\u0131\u011fa \u00e7\u0131kar\u0131r.<\/li>\n
  3. Karma\u015f\u0131k \u015eifreleme Boru Hatlar\u0131:<\/strong> GPG kullanarak yedekleri an\u0131nda \u015fifrelemeye \u00e7al\u0131\u015fmak, ciddi CPU y\u00fck\u00fc ve anahtar y\u00f6netimi karma\u015f\u0131kl\u0131klar\u0131 getirir.<\/li>\n<\/ol>\n

    Sunucu ele ge\u00e7irilirse, sald\u0131rgan hem \u015fifreli yede\u011fe hem de \/etc\/keys\/backup.key<\/code> dosyas\u0131na eri\u015febilir ve bu da \u015fifrelemeyi i\u015fe yaramaz hale getirir. Ayr\u0131ca, GPG anahtar\u0131n\u0131 olu\u015fturan DBA \u015firketten ayr\u0131l\u0131rsa ve anahtar kaybolursa, yedekler kurtar\u0131lamaz hale gelir.<\/p>\n
    Tehlike 5: RTO Ger\u00e7eklik Kontrol\u00fc (Geri Y\u00fckleme, Yedeklemekten Daha Zordur)<\/h2>\n
    Bir yede\u011fin nihai testi geri y\u00fcklemedir.

Bu saatler, hatta g\u00fcnler s\u00fcrebilir ve RTO’nuzu yok edebilir.<\/p>\n
    B\u00fcy\u00fck \u00fcretim veritabanlar\u0131 i\u00e7in fiziksel yedeklemeler (ger\u00e7ek veri dosyalar\u0131n\u0131 kopyalamak) zorunludur. Percona XtraBackup veya pg_basebackup<\/code> gibi ara\u00e7lar mevcut olsa da, bunlar\u0131 DIY Bash betikleriyle sarmalamak olduk\u00e7a karma\u015f\u0131kt\u0131r.

    Betiklerden Uzakla\u015fman\u0131n Temel Avantajlar\u0131:<\/h3>\n
      \n
    1. Otomatik Do\u011frulama:<\/strong> Modern platformlar sadece yedekleme yapmaz; onlar\u0131 test eder. CloudSave, ge\u00e7ici bir veritaban\u0131 \u00f6rne\u011fini otomatik olarak ba\u015flatabilir, yede\u011fi geri y\u00fckleyebilir, tutarl\u0131l\u0131k kontrolleri (\u00f6rne\u011fin DBCC CHECKDB<\/code>) \u00e7al\u0131\u015ft\u0131rabilir ve ard\u0131ndan \u00f6rne\u011fi kapatarak yede\u011fin ger\u00e7ekten kullan\u0131labilir oldu\u011funa dair do\u011frulanm\u0131\u015f bir rapor sunabilir.<\/li>\n
    2. De\u011fi\u015ftirilemez (Immutable) Depolama:<\/strong> Fidye yaz\u0131l\u0131mlar\u0131yla m\u00fccadele etmek i\u00e7in yedeklerin de\u011fi\u015ftirilemez olmas\u0131 gerekir. DIY betikleri WORM (Bir Kez Yaz, \u00c7ok Kez Oku) depolamaya kolayca yazamaz. Kurumsal \u00e7\u00f6z\u00fcmler, S3 Object Lock ve de\u011fi\u015ftirilemez bulut depolama ile yerel olarak entegre olur ve bir sunucu tamamen ele ge\u00e7irilse bile yedeklerin bir sald\u0131rgan taraf\u0131ndan silinememesini veya \u015fifrelenememesini sa\u011flar.<\/li>\n
    3. Basitle\u015ftirilmi\u015f PITR:<\/strong> Karma\u015f\u0131k recovery.conf<\/code> veya postgresql.auto.conf<\/code> parametrelerini kullanarak bir temel yedekleme ile y\u00fczlerce WAL dosyas\u0131n\u0131 manuel olarak birle\u015ftirmek yerine, platformlar g\u00f6rsel bir zaman \u00e7izelgesi sa\u011flar. Geri y\u00fcklemek istedi\u011finiz tam dakikay\u0131 se\u00e7ersiniz ve yaz\u0131l\u0131m g\u00fcnl\u00fck tekrar\u0131n\u0131 (log replay) otomatik olarak halleder.<\/li>\n
    4. Tekille\u015ftirme ve S\u0131k\u0131\u015ft\u0131rma:<\/strong> DIY betikleri, her dosyay\u0131 ayr\u0131 ayr\u0131 s\u0131k\u0131\u015ft\u0131ran gzip<\/code>‘e g\u00fcvenir. Kurumsal yedekleme yaz\u0131l\u0131mlar\u0131, yedekleri tesis d\u0131\u015f\u0131na aktar\u0131rken depolama maliyetlerini ve a\u011f bant geni\u015fli\u011fini \u00f6nemli \u00f6l\u00e7\u00fcde azaltan k\u00fcresel blok d\u00fczeyinde tekille\u015ftirme kullan\u0131r.<\/li>\n<\/ol>\n
      Sonu\u00e7<\/h2>\n
      Bir veritaban\u0131n\u0131 yedeklemek i\u00e7in \u00f6zel bir Bash beti\u011fi yazmak kolayd\u0131r. Sessiz boru hatt\u0131 hatalar\u0131n\u0131 y\u00f6neten, ACID tutarl\u0131l\u0131\u011f\u0131n\u0131 garanti eden, kriptografik anahtarlar\u0131 g\u00fcvenli bir \u015fekilde y\u00f6neten, saklama tabanl\u0131 veri kayb\u0131n\u0131 \u00f6nleyen ve kat\u0131 RTO\/RPO SLA’lerini garanti eden bir betik yazmak neredeyse imkans\u0131zd\u0131r.<\/p>\n
      \u00dcretim ortamlar\u0131nda veritaban\u0131, i\u015fletmenin en kritik varl\u0131\u011f\u0131d\u0131r. Korunmas\u0131n\u0131 birka\u00e7 y\u00fcz sat\u0131rl\u0131k kabuk beti\u011fi taraf\u0131ndan s\u00fcrd\u00fcr\u00fclen bir yan proje olarak g\u00f6rmek, hi\u00e7bir i\u015fletmenin g\u00f6ze alamayaca\u011f\u0131 bir risktir. Mevcut yedekleme stratejilerinizi denetleyerek, mant\u0131ksal dump’lar\u0131n s\u0131n\u0131rlamalar\u0131n\u0131 anlayarak ve CloudSave gibi sa\u011flam, otomatik platformlara ge\u00e7i\u015f yaparak, DevOps ve DBA ekipleri \u00f6zel betiklerin “otob\u00fcs fakt\u00f6r\u00fcn\u00fc” (bir ki\u015finin ayr\u0131lmas\u0131yla bilginin kaybolmas\u0131) ortadan kald\u0131rabilir ve verilerinin ger\u00e7ekten diren\u00e7li oldu\u011fundan emin olabilirler.<\/p>\n","protected":false},"excerpt":{"rendered":"
