Selles artiklis r\u00e4\u00e4gin, kuidas ma tutvusin Quest Netvault Backupiga. Olin kuulnud Netvault Backapi kohta palju positiivseid arvustusi, kui see tarkvara kuulus veel Dellile, kuid mul ei olnud eelnevalt olnud v\u00f5imalust seda ise k\u00e4ega katsuda.<\/p>\n

Quest Software, tuntud ka kui Quest, on Californias asuv tarkvarafirma, millel on 53 kontorit 24 riigis. Asutatud 1987. aastal. Ettev\u00f5te on tuntud oma tarkvara poolest, mida kasutavad andmebaasi spetsialistid, pilvehalduse valdkonnas, infoturbe alal, andmeanal\u00fc\u00fcsiks ning varundamiseks ja taastamiseks. Quest Software omandas Dell 2012. aastal. 1. novembriks 2016 l\u00f5petati m\u00fc\u00fck ja ettev\u00f5te k\u00e4ivitus Quest Softwareina uuesti.<\/p>\n

Tutvus Quest Netvaultiga toimus hiljuti. \u00dches projektis palus klient leida taskukohane ja optimaalne lahendus oma infrastruktuuri kaitsmiseks. Klient kaalus erinevaid varundustarkvarasid, mille seas oli Quest Netvault Backup. Testide tulemuste p\u00f5hjal, arvestades kliendi jaoks olulisi parameetreid (millest osa on toodud artikli l\u00f5pus), valiti Quest Netvault Backup.
\nPeamistele n\u00f5udmistele lisaks soovis klient, et tarkvara paigaldataks Linuxi serveritesse. Selliseid n\u00f5udeid ei t\u00e4ida k\u00f5ik varundustarkvarad, kuid Quest Netvault Backup suudab seda teha.<\/p>\n

Algandmed ja n\u00f5udmised<\/h4>\n

\nKliendi p\u00fcstitatud \u00fclesanne oli projekteerida s\u00fcsteem, mis tagab 62 TB andmete varundamise. Need andmed asusid rakenduss\u00fcsteemides nagu SAP, Microsoft SQL, PostgreSQL, MariaDB, Microsoft Exchange, Microsoft SharePoint jne. Need rakenduss\u00fcsteemid t\u00f6\u00f6tasid f\u00fc\u00fcsilistes ja virtuaalsetes serverites, mis kasutasid Microsoft Windows Serveri, Linuxi ja FreeBSD operatsioonis\u00fcsteeme. Virtuaalne keskkond p\u00f5hines VMware vSphere virtualiseerimisplatvormil. Infrastruktuur asus \u00fches asukohas. <\/p>\n

\u00dcldiselt on kliendi infrastruktuur esitatud joonisel 1.1.<\/p>\n

Anal\u00fc\u00fcsi k\u00e4igus uuriti Quest Netvault Backupi v\u00f5imalusi, mis on rakendatavad Kliendi infrastruktuuri suhtes, nimelt: andmete varundamise, taastamise, haldamise ja j\u00e4lgimise osas. T\u00fc\u00fcpiline funktsionaalsus ja t\u00f6\u00f6p\u00f5him\u00f5tted ei erine praktiliselt teiste tarnijate tarkvarast. Seet\u00f5ttu soovin peatuda Quest Netvault Backupi erilistel omadustel, mis eristavad seda teistest varundustarkvaradest.<\/p>\n

Huvitavad omadused<\/h4>\n

\nPaigaldamine<\/p>\n

Quest Netvault Backupi distributsiooni suurus on vaid 254 megabaiti, mis v\u00f5imaldab seda kiiresti rakendada. <\/p>\n

Toetatud platvormide ja \u00fclesannete pluginad laetakse eraldi, kuid see avaldab positiivset m\u00f5ju s\u00fcsteemi sihtele, mis sisaldab ainult vajalikku funktsionaalsust konkreetse infrastruktuuri kaitsmiseks ja ei ole koormatud liigsete v\u00f5imalustega. <\/p>\n

Haldamine<\/p>\n

Netvaulti haldamine k\u00e4ib veebliidese WebUI kaudu. Sisse logimine toimub kasutajanime ja parooli abil.<\/p>\n

\"Otsides
\nJoonis 1.2 \u2013 Juhtimist konsooli sisselogimise aken<\/p>\n

Veebikonsoliga \u00fchendust saab luua igast arvutist, mis on \u00fchendatud v\u00f5rguga, kasutades brauserit. <\/p>\n

WebUI-s kasutatakse lihtsat ja kasutaj s\u00f5bralikku liidest, haldamine ei tekita mingeid probleeme, juhtimise loogika on arusaadav ja selge; kui k\u00fcsimusi siiski tekib, siis on tootja veebisaidil saadaval p\u00f5hjalik toote dokumentatsioon<\/a><\/noindex>.

\nJoonis 1.3 \u2013 WebUI liides<\/p>\n

WebUI on m\u00f5eldud Quest Netvault Backupi haldamiseks ja j\u00e4lgimiseks ning v\u00f5imaldab t\u00e4ita j\u00e4rgmisi \u00fclesandeid:
\n\u2013 j\u00f5udluse, turvalisuse ja muude parameetrite seadistamine;

\u2013 teavituste seadistamine;
\n\u2013 aruannete koostamine ja vaatamine.<\/p>\n

Salvestusseadmed<\/p>\n

Quest Netvault rakendab h\u00f5lpsasti 3-2-1 s\u00e4ilitamisreeglit, kuna suudab t\u00f6\u00f6tada nii hetkeandmete varukoopiate seadmetega (andmesalvestuss\u00fcsteemid) kui ka pikaajalise s\u00e4ilitamise seadmetega (dedupilatsiooniseadmed, f\u00fc\u00fcsilised lintraamatukogud, automaatsed laadijad, virtuaalsed lintraamatukogud (VTL) ja \u00fchiskasutatavad virtuaalsed lintraamatukogud (SVTL)). Omandivabade varukoopiate s\u00e4ilitamine on v\u00f5imalik pilves, eemal asuvas kohas v\u00f5i omandivabal andmekandjal (n\u00e4iteks lindi salvestis). <\/p>\n

Dedupilatsiooniseadmetega t\u00f6\u00f6tamisel toetatakse spetsialiseeritud protokolle RDA ja DD Boost. Nende protokollide kasutamine:
\n\u2013 v\u00e4hendab v\u00f5rgu koormust ja suurendab varundamis\u00fclesannete j\u00f5udlust, kuna andmed dedupilatsiooni k\u00e4igus kliendis ja edastatakse ainult vajalikud plokid. N\u00e4iteks koos Quest Qorestoriga RDA protokolli kaudu t\u00f6\u00f6tamine v\u00f5imaldab saavutada j\u00f5udlust kuni 20 terabaiti tunnis ja 20:1 kokkusurumise suhte;
\n\u2013 kaitseb varukoopiaid kr\u00fcptoviiruste eest. I isegi kui varukoopia server on nakatunud ja kr\u00fcptitud, j\u00e4\u00e4vad varukoopiad puutumatuks. lingil<\/a><\/noindex>.<\/p>\n

Kliendid<\/p>\n

Quest Netvault Backup toetab enam kui kolmek\u00fcmmet platvormi ja rakendust. \u00dcksikasjadesse saab tutvuda m\u00fc\u00fcgiesindaja veebisaidil lingil<\/a><\/noindex> (Joonis 1.7). Protecting systems compatibility check with Quest Netvault Backup is conducted according to the official document \u201cQuest Netvault Backup Compatibility Guide\u201d, which can be found at lingil<\/a><\/noindex>.<\/p>\n

Nii paljude s\u00fcsteemide tugi v\u00f5imaldab projekteerida lahendusi keerukatele Enterprise taseme infrastruktuuridele. Klientide jagamine toimub pluginade kaudu (analoog teistel m\u00fc\u00fcjatel - agendid), mis installitakse serveritele. L\u00f5puks kaitstakse andmeid \u00fche s\u00fcsteemi kaudu \u00fche halduspunktega.<\/p>\n

\nLisaks pluginatele platvormidele, mis t\u00f6\u00f6tavad eraldi serverites, on Quest Netvault Backup ka versioonid pluginatest, mis toetavad erinevaid klastris\u00fcsteeme. Sellisel juhul r\u00fchmitatakse klastris\u00f5lmed virtuaalseks kliendiks, millele installitakse klastri toetav plugin. Klastri s\u00f5lmede varundamine ja taastamine viiakse l\u00e4bi juba selle virtuaalse kliendi kaudu. Allpool on tabelis esitatud klasterversioonide pluginad.<\/p>\n

Pikaajalise s\u00e4ilitamise jaoks kasutati LTO-7 standardi nelja draiviga lintraamatukogu. Lintkaust \u00fchendati varukoopia serveriga SAS-i kaudu. Aeg-ajalt eemaldati kassetid ja viidi hoiule \u00fchte kaugfiliaali.<\/p>\n
