Backup & Recovery de W. Curtis Preston

Backup & Recovery

Autor W. Curtis Preston
en Limba Engleză Paperback – 6 feb 2007

Ecosistemul tehnic analizat în Backup & Recovery este unul vast, axat pe soluții practice și accesibile pentru protecția datelor. Găsim în această carte o documentație extinsă pentru utilitarele fundamentale de sistem, precum tar, dump, cpio, ntbackup sau rsync, dar și pentru produse open source complexe care automatizează aceste procese, cum sunt AMANDA, Bacula sau BackupPC. Autorul W. Curtis Preston propune o abordare care prioritizează independența de soluțiile comerciale costisitoare, oferind alternative robuste pentru Unix, Linux, Windows și Mac OS X. Subliniem importanța secțiunilor dedicate procedurilor de „bare metal recovery”, esențiale pentru restabilirea completă a sistemelor AIX, HP-UX, Solaris sau VMWare direct pe hardware-ul original sau nou. Cartea nu se limitează doar la fișiere, ci extinde aplicabilitatea tehnicilor asupra bazelor de date critice, precum MySQL, PostgreSQL, Oracle și SQL-Server. Abordarea diferă de Pro Data Backup and Recovery prin faptul că este mai puțin abstractă și mult mai aplicabilă; în timp ce Steven Nelson se concentrează pe arhitecturi de mari dimensiuni și software comercial precum NetBackup, volumul de față oferă instrucțiuni concrete pentru implementarea unor sisteme de protecție folosind instrumente gratuite și disponibile imediat. Merită menționat că textul include și o analiză a tehnologiilor moderne de stocare, explicând concepte precum deduplicarea datelor, Continuous Data Protection (CDP) și Virtual Tape Libraries (VTL). Față de ediția sa anterioară, volumul este revizuit în proporție de 75%, devenind un manual tehnic indispensabil pentru administratorii care gestionează medii eterogene și bugete stricte.

Descriere

Packed with practical, freely available backup and recovery solutions for Unix, Linux, Windows, and Mac OS X systems -- as well as various databases -- this new guide is a complete overhaul of Unix Backup & Recovery by the same author, now revised and expanded with over 75% new material.Backup & Recovery starts with a complete overview of backup philosophy and design, including the basic backup utilities of tar, dump, cpio, ntbackup, ditto, and rsync. It then explains several open source backup products that automate backups using those utilities, including AMANDA, Bacula, BackupPC, rdiff-backup, and rsnapshot. Backup & Recovery then explains how to perform bare metal recovery of AIX, HP-UX, Linux, Mac OS, Solaris, VMWare, & Windows systems using freely-available utilities. The book also provides overviews of the current state of the commercial backup software and hardware market, including overviews of CDP, Data De-duplication, D2D2T, and VTL technology. Finally, it covers how to automate the backups of DB2, Exchange, MySQL, Oracle, PostgreSQL, SQL-Server, and Sybase databases - without purchasing a commercial backup product to do so.For environments of all sizes and budgets, this unique book shows you how to ensure data protection without resorting to expensive commercial solutions. You will soon learn to:Automate the backup of popular databases without a commercial utilityPerform bare metal recovery of any popular open systems platform, including your PC or laptopUtilize valuable but often unknown open source backup productsUnderstand the state of commercial backup software, including explanations of CDP and data de-duplication softwareAccess the current state of backup hardware, including Virtual Tape Libraries (VTLs)
