Kiekvienas duomen\u0173 bazi\u0173 administratorius (DBA) ir sistem\u0173 in\u017einierius savo karjeroje bent kart\u0105 yra para\u0161\u0119s pasirinktin\u012f \u201eshell\u201c scenarij\u0173 duomen\u0173 bazei kurti.

Ta\u010diau infrastrukt\u016brai ple\u010diantis, duomen\u0173 kiekiui augant, o veikimo laiko (uptime) SLA (paslaug\u0173 kokyb\u0117s susitarimams) tampant grie\u017etesniems, tas 10 eilu\u010di\u0173 \u201eBash\u201c scenarijus tyliai virsta tiksin\u010dia bomba.

Pasikliovimas savadarbiais atsargini\u0173 kopij\u0173 scenarijais \u0161iose aplinkose sukelia rimt\u0105 rizik\u0105, susijusi\u0105 su duomen\u0173 vientisumu, nepastebimais gedimais, saugumo spragomis ir nevaldomais atk\u016brimo procesais.<\/p>\n

\u0160iame straipsnyje i\u0161nagrin\u0117sime architekt\u016brinius tr\u016bkumus ir pasl\u0117ptus savadarbi\u0173 duomen\u0173 bazi\u0173 atsargini\u0173 kopij\u0173 scenarij\u0173 pavojus, aptarsime technines logini\u0173 ir fizini\u0173 atsargini\u0173 kopij\u0173 problemas bei tai, kaip pereiti prie verslo klas\u0117s sprendim\u0173, toki\u0173 kaip \u201eCloudSave\u201c, siekiant apsaugoti j\u016bs\u0173 verslui kritinius duomenis.<\/p>\n

Paprastumo iliuzija: savadarbio scenarijaus anatomija<\/h2>\n

Nor\u0117dami suprasti pavoj\u0173, pirmiausia turime pa\u017evelgti \u012f tipinio savadarbio atsargini\u0173 kopij\u0173 scenarijaus strukt\u016br\u0105. Standartinis po\u017ei\u016bris \u012f \u201eMySQL\u201c duomen\u0173 baz\u0119 da\u017enai atrodo taip:<\/p>\n

#!\/bin\/bash\n# Paprastas savadarbis MySQL atsargini\u0173 kopij\u0173 scenarijus\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# I\u0161trinti senesnes nei 30 dien\u0173 atsargines kopijas\nfind $BACKUP_DIR -type f -name \"*.sql.gz\" -mtime +30 -exec rm {} ;\n<\/code><\/pre>\n
I\u0161 pirmo \u017evilgsnio \u0161is scenarijus atlieka savo darb\u0105: i\u0161traukia duomenis, juos suspaud\u017eia ir tvarko saugojimo laikotarp\u012f. Ta\u010diau po pavir\u0161iumi jis kupinas kritini\u0173 tr\u016bkum\u0173, kurie gamybin\u0117je aplinkoje ilgainiui sukels duomen\u0173 praradim\u0105.<\/p>\n
1 pavojus: nepastebimi gedimai ir \u201epipe\u201c sp\u0105stai<\/h2>\n
Vienas klastingiausi\u0173 savadarbi\u0173 scenarij\u0173 pavoj\u0173 yra nepastebimi gedimai. Auk\u0161\u010diau pateiktame scenarijuje mysqldump<\/code> komanda nukreipiama (|<\/code>) tiesiai \u012f gzip<\/code>.<\/p>\n
\u201eBash\u201c aplinkoje konvejerio (pipeline) i\u0161\u0117jimo b\u016bsena yra paskutin\u0117s<\/em> konvejerio komandos i\u0161\u0117jimo b\u016bsena. Jei duomen\u0173 baz\u0117s serveryje baigiasi atmintis, nutr\u016bksta ry\u0161ys arba pusiaukel\u0117je aptinkama u\u017erakinta lentel\u0117, mysqldump<\/code> nepavyks ir bus i\u0161mesta klaida. Ta\u010diau gzip<\/code> s\u0117kmingai suspaus gaut\u0105 dalin\u012f i\u0161vesties rezultat\u0105 ir baigs darb\u0105 su b\u016bsenos kodu 0<\/code> (s\u0117km\u0117).<\/p>\n
J\u016bs\u0173 steb\u0117jimo sistema, tikrinanti \u201ecron\u201c u\u017eduoties i\u0161\u0117jimo kod\u0105, prane\u0161 apie s\u0117kming\u0105 atsargin\u0119 kopij\u0105. Diske tur\u0117site galiojant\u012f .gz<\/code> fail\u0105, ta\u010diau jo viduje bus sugadintas, nenaudingas SQL failas. Tai su\u017einosite tik tada, kai bandysite atlikti kritin\u012f atk\u016brim\u0105.<\/p>\n
\u0160velninimo priemon\u0117s (ir j\u0173 ribos)<\/h3>\n
In\u017einieriai da\u017enai bando tai i\u0161taisyti \u012fjungdami grie\u017et\u0105 klaid\u0173 apdorojim\u0105 \u201eBash\u201c:<\/p>\n
set -e\nset -o pipefail\n<\/code><\/pre>\n
Nors set -o pipefail<\/code> u\u017etikrina, kad scenarijus nutr\u016bkt\u0173, jei nepavyksta bet kuri<\/em> konvejerio komanda, vis tiek reikia sukurti patikimus \u012fsp\u0117jimo, registravimo ir pakartotinio bandymo mechanizmus. Kai d\u0117l laikino tinklo gedimo 2:00 val. nakties \u012fvyksta klaida, savadarbis scenarijus tiesiog nutr\u016bksta. Verslo platformos tokias laikinas klaidas sprend\u017eia naudodamos i\u0161manius, eksponentinius pakartotinius bandymus.<\/p>\n
2 pavojus: duomen\u0173 vientisumas ir u\u017erakinimo ko\u0161marai<\/h2>\n
Savadarbiai scenarijai labai priklauso nuo logini\u0173 atsargini\u0173 kopij\u0173 (mysqldump<\/code>, pg_dump<\/code>). Login\u0117s atsargin\u0117s kopijos i\u0161traukia duomenis vykdydamos SELECT<\/code> u\u017eklausas visose lentel\u0117se. Labai transakcin\u0117je gamybin\u0117je duomen\u0173 baz\u0117je duomenys nuolat kei\u010diasi. Jei scenarijus 100 GB duomen\u0173 baz\u0117s kopijavimui u\u017etrunka 45 minutes, duomenys kopijos prad\u017eioje bus 45 minut\u0117mis senesni nei duomenys pabaigoje, taip pa\u017eeid\u017eiant ACID reikalavimus.<\/p>\n
MySQL transakcij\u0173 vientisumas<\/h3>\n
Norint pasiekti vientis\u0105 \u201eMySQL\u201c momentin\u0119 kopij\u0105 naudojant \u201eInnoDB\u201c, b\u016btina nurodyti specifinius parametrus:<\/p>\n
mysqldump --single-transaction --quick --routines --events -u user -p db > dump.sql\n<\/code><\/pre>\n
Parametras --single-transaction<\/code> nustato izoliacijos lyg\u012f \u012f REPEATABLE READ<\/code> ir pradeda transakcij\u0105 prie\u0161 kopijavim\u0105. Ta\u010diau, jei j\u016bs\u0173 duomen\u0173 baz\u0117je vis dar yra sen\u0173 \u201eMyISAM\u201c lenteli\u0173, \u0161is parametras neapsaugos nuo j\u0173 u\u017erakinimo, o tai gali sustabdyti gamybin\u012f skaitymo\/ra\u0161ymo sraut\u0105 kopijavimo metu. Be to, bet kokios ALTER TABLE<\/code>, DROP TABLE<\/code> ar RENAME TABLE<\/code> komandos, kurias k\u016br\u0117jai \u012fvykdys kopijavimo metu, sugadins REPEATABLE READ<\/code> momentin\u0119 kopij\u0105, tod\u0117l kopijavimas nepavyks.<\/p>\n
PostgreSQL ir WAL archyvavimas<\/h3>\n
\u201ePostgreSQL\u201c atveju pg_dump<\/code> suteikia vientisas logines atsargines kopijas, ta\u010diau vien login\u0117s kopijos negali u\u017etikrinti atk\u016brimo iki tam tikro laiko momento (PITR). Jei j\u016bs\u0173 duomen\u0173 baz\u0117 sugenda 16:00 val., o paskutinis \u201ecron\u201c scenarijus veik\u0117 vidurnakt\u012f, prarasite 16 valand\u0173 duomen\u0173.<\/p>\n
PITR pasiekimui reikalingas nuolatinis \u201eWrite-Ahead Logs\u201c (WAL) archyvavimas. Para\u0161yti savadarb\u012f scenarij\u0173, kuris saugiai tvarkyt\u0173 archive_command<\/code>, yra itin sud\u0117tinga.<\/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
Jei paskirties saugykla (\/mnt\/wal_archive\/<\/code>) u\u017esipildo arba tampa nepasiekiama, archive_command<\/code> nepavyks. Tada \u201ePostgreSQL\u201c kaups WAL failus lokaliai, kol u\u017esipildys pagrindinis diskas, o tai sukels visi\u0161k\u0105 duomen\u0173 baz\u0117s veiklos sutrikim\u0105. Savadarbiai scenarijai retai turi telemetrij\u0105, reikaling\u0105 WAL kaupimosi steb\u0117jimui ir administratori\u0173 \u012fsp\u0117jimui prie\u0161 \u012fvykstant gedimui.<\/p>\n
3 pavojus: saugojimo laikotarpio rulet\u0117<\/h2>\n
Pa\u017evelkite atgal \u012f saugojimo komand\u0105 m\u016bs\u0173 pradiniame scenarijuje:<\/p>\n
find $BACKUP_DIR -type f -name \"*.sql.gz\" -mtime +30 -exec rm {} ;\n<\/code><\/pre>\n
Tai katastrofi\u0161ko duomen\u0173 praradimo scenarijus. \u012esivaizduokite situacij\u0105, kai konfig\u016bracijos pakeitimas sugadina mysqldump<\/code> autentifikavim\u0105. Scenarijus nebegali sukurti nauj\u0173 atsargini\u0173 kopij\u0173, ta\u010diau find<\/code> komanda ir toliau veikia kiekvien\u0105 nakt\u012f, s\u0105\u017einingai trindama senesnius nei 30 dien\u0173 failus.<\/p>\n
Po 30 dien\u0173 tyli\u0173 atsargini\u0173 kopij\u0173 k\u016brimo nes\u0117kmi\u0173 find<\/code> komanda i\u0161trins j\u016bs\u0173 paskutin\u0119 likusi\u0105 ger\u0105 atsargin\u0119 kopij\u0105. J\u016bs liksite be joki\u0173 atsargini\u0173 kopij\u0173.<\/p>\n
Verslo klas\u0117s atsargini\u0173 kopij\u0173 programin\u0117 \u012franga, tokia kaip \u201eCloudSave\u201c, naudoja b\u016bsenos saugojimo politikas. Ji supranta skirtum\u0105 tarp \u201ei\u0161trinti senesnes nei 30 dien\u0173 kopijas\u201c ir \u201eu\u017etikrinti, kad prie\u0161 \u0161alinant senus duomenis egzistuoja bent 30 s\u0117kming\u0173 atk\u016brimo ta\u0161k\u0173\u201c.<\/p>\n
4 pavojus: saugumas, \u0161ifravimas ir atitikties spragos<\/h2>\n
I\u0161pirkos reikalaujan\u010di\u0173 virus\u0173 ir grie\u017et\u0173 atitikties sistem\u0173 (BDAR, HIPAA, SOC 2) eroje atsargin\u0117s kopijos yra pagrindinis taikinys. Savadarbiai scenarijai da\u017enai pa\u017eeid\u017eia geriausi\u0105 saugumo praktik\u0105:<\/p>\n
    \n
  1. \u012era\u0161yti kredencialai:<\/strong> Duomen\u0173 baz\u0117s slapta\u017eod\u017ei\u0173 laikymas paprastu tekstu scenarijuose ar \u201ecron\u201c apibr\u0117\u017eimuose yra did\u017eiul\u0117 saugumo rizika. Nors tokie \u012frankiai kaip \u201eMySQL\u201c mysql_config_editor<\/code> ar \u201ePostgreSQL\u201c .pgpass<\/code> failas tai su\u0161velnina, jie vis tiek reikalauja valdyti vietinius rakt\u0173 failus serveryje.<\/li>\n
  2. \u0160ifravimo ramyb\u0117s b\u016bsenoje tr\u016bkumas:<\/strong> Neapdoroto SQL i\u0161metimas \u012f disk\u0105 palieka jautrius PII\/PHI duomenis atvirus.<\/li>\n
  3. Sud\u0117tingi \u0161ifravimo konvejeriai:<\/strong> Bandymai \u0161ifruoti atsargines kopijas skryd\u017eio metu naudojant GPG sukelia didel\u0119 procesoriaus apkrov\u0105 ir rakt\u0173 valdymo sud\u0117tingum\u0105.<\/li>\n<\/ol>\n
    # Savadarbis \u0161ifruot\u0173 atsargini\u0173 kopij\u0173 konvejeris\npg_dump mydb | gzip | gpg --symmetric --cipher-algo AES256 --passphrase-file \/etc\/keys\/backup.key > backup.sql.gz.gpg\n<\/code><\/pre>\n
    Jei serveris yra kompromituotas, u\u017epuolikas gauna prieig\u0105 ir prie \u0161ifruotos atsargin\u0117s kopijos, ir prie \/etc\/keys\/backup.key<\/code> failo, tod\u0117l \u0161ifravimas tampa bevertis. Be to, jei GPG rakt\u0105 sugenerav\u0119s DBA palieka \u012fmon\u0119 ir raktas prarandamas, atsargin\u0117s kopijos tampa neatkuriamos.<\/p>\n
    5 pavojus: RTO realyb\u0117s patikrinimas (atkurti sunkiau nei kopijuoti)<\/h2>\n
    Galutinis atsargin\u0117s kopijos patikrinimas yra atk\u016brimas. Savadarbi\u0173 scenarij\u0173 sukurtas logines atsargines kopijas atkurti yra itin l\u0117ta. 500 GB SQL kopijos suk\u016brimas gali u\u017etrukti 15 minu\u010di\u0173, ta\u010diau jos atk\u016brimas reikalauja, kad duomen\u0173 baz\u0117s variklis i\u0161analizuot\u0173 SQL, perstatyt\u0173 indeksus ir perskai\u010diuot\u0173 apribojimus. Tai gali u\u017etrukti valandas ar net dienas, sunaikinant j\u016bs\u0173 RTO.<\/p>\n
    Didel\u0117ms gamybin\u0117ms duomen\u0173 baz\u0117ms fizin\u0117s atsargin\u0117s kopijos (faktini\u0173 duomen\u0173 fail\u0173 kopijavimas) yra privalomos. Nors egzistuoja tokie \u012frankiai kaip \u201ePercona XtraBackup\u201c ar pg_basebackup<\/code>, j\u0173 \u012ftraukimas \u012f savadarbius \u201eBash\u201c scenarijus yra labai sud\u0117tingas. Turite valdyti LVM momentines kopijas, tvarkyti fail\u0173 sistemos u\u017e\u0161aldym\u0105 ir u\u017etikrinti, kad atsargin\u0117 kopija b\u016bt\u0173 perkelta u\u017e serverio rib\u0173 neapkraunant tinklo s\u0105sajos.<\/p>\n
    LVM momentin\u0117s kopijos sp\u0105stai<\/h3>\n
    Daugelis in\u017einieri\u0173 bando atlikti \u201enulin\u0117s prastovos\u201c fizines atsargines kopijas naudodami LVM momentines kopijas:<\/p>\n
    # Sukurti momentin\u0119 kopij\u0105\nlvcreate --size 20G --snapshot --name db_snap \/dev\/vg0\/db_vol\n\n# Prijungti ir nukopijuoti\nmount \/dev\/vg0\/db_snap \/mnt\/snap\ntar -czf \/backups\/db_physical.tar.gz \/mnt\/snap\/mysql\n<\/code><\/pre>\n
    Jei duomen\u0173 baz\u0117je staiga padid\u0117ja ra\u0161ymo I\/O, 20 GB LVM momentin\u0117 kopija gali akimirksniu u\u017esipildyti. Kai LVM momentin\u0117 kopija u\u017esipildo, ji tampa negaliojan\u010dia ir atsargin\u0117s kopijos k\u016brimas nepavyksta. Dar blogiau, intensyviai naudojamos LVM momentin\u0117s kopijos gali smarkiai pabloginti pagrindinio duomen\u0173 baz\u0117s tomo I\/O na\u0161um\u0105, sukeldamos programos v\u0117lavimo \u0161uolius.<\/p>\n
    Per\u0117jimas prie verslo klas\u0117s apsaugos<\/h2>\n
    Per\u0117jimas nuo savadarbi\u0173 scenarij\u0173 prie verslo platformos yra kritinis brandos etapas bet kuriai infrastrukt\u016bros komandai. Tikslas yra pereiti nuo \u201etik\u0117jimosi, kad scenarijus suveik\u0117\u201c prie kriptografinio atk\u016brimo galimyb\u0117s \u012frodymo.<\/p>\n
    Tokios platformos kaip \u201eCloudSave\u201c yra sukurtos specialiai tam, kad pa\u0161alint\u0173 savadarbi\u0173 scenarij\u0173 akl\u0105sias zonas. Diegdama programoms pritaikytus agentus, \u201eCloudSave\u201c tiesiogiai s\u0105veikauja su duomen\u0173 bazi\u0173 API (\u201eMySQL\u201c, \u201ePostgreSQL\u201c, \u201eMS SQL\u201c, \u201eOracle\u201c), kad suderint\u0173 vientisas fizines ir logines atsargines kopijas be lenteli\u0173 u\u017erakinimo ar na\u0161umo ma\u017einimo.<\/p>\n
    Pagrindiniai atsisakymo nuo scenarij\u0173 privalumai:<\/h3>\n
      \n
    1. Automatizuotas patikrinimas:<\/strong> \u0160iuolaikin\u0117s platformos ne tik kuria atsargines kopijas; jos jas tikrina. \u201eCloudSave\u201c gali automati\u0161kai paleisti laikin\u0105 duomen\u0173 baz\u0117s egzempliori\u0173, atkurti atsargin\u0119 kopij\u0105, atlikti vientisumo patikrinimus (pvz., DBCC CHECKDB<\/code>) ir j\u0105 i\u0161jungti, pateikdama patvirtint\u0105 ataskait\u0105, kad atsargin\u0117 kopija yra tikrai tinkama naudoti.<\/li>\n
    2. Nekintanti saugykla:<\/strong> Kovai su i\u0161pirkos reikalaujan\u010diais virusais atsargin\u0117s kopijos turi b\u016bti nekintan\u010dios. Savadarbiai scenarijai negali lengvai ra\u0161yti \u012f WORM (Write Once, Read Many) saugyklas. Verslo sprendimai nat\u016braliai integruojasi su \u201eS3 Object Lock\u201c ir nekintan\u010dia debes\u0173 saugykla, u\u017etikrindami, kad net jei serveris b\u016bt\u0173 visi\u0161kai kompromituotas, atsargini\u0173 kopij\u0173 u\u017epuolikas negal\u0117t\u0173 i\u0161trinti ar u\u017e\u0161ifruoti.<\/li>\n
    3. Supaprastintas PITR:<\/strong> U\u017euot rankiniu b\u016bdu sujungus bazin\u0119 atsargin\u0119 kopij\u0105 ir \u0161imtus WAL fail\u0173 naudojant sud\u0117tingus recovery.conf<\/code> ar postgresql.auto.conf<\/code> parametrus, platformos pateikia vizuali\u0105 laiko juost\u0105.
