This document provides an overview of Bacula, an open source network backup solution. It describes the main Bacula components including the Bacula Director, Console, File, Storage, Catalog, and Monitor services. It also discusses how Bacula allows for centralized backup/restore, scheduling, job prioritization, security features, restoration capabilities, storage device support, operating system support, and graphical user interfaces. The document concludes by announcing $4.5 million in funding for Bacula Systems to deliver enterprise-grade open source backup and restoration technologies to large data centers.

2. Bacula Components or Services
● Bacula Director
● Bacula Console
● Bacula File
● Bacula Storage
● Catalog
● Bacula Monitor

4. ● Bacula Director
- supervizeaza operatiunile de backup, restore, verify si archive
● Bacula Console
- permite comunicarea cu Bacula Director
- poate fi o consola text, interfata QT-based sau wxWidgets
● Bacula File (clientul)
- livreaza atributele fisierelor, data, acl; comprima si cripteaza
fisierele

5. ● Bacula Storage
- salvare, restaurare a fisierelor, atributelor, acl (de) pe disc, tape,
dvd
● Catalog
- mentine un index a fisierelor salvate
- cautare si gasire usoara/rapida a fisierelor
- mentine inregistrari a volumelor utilizate, a job-urilor rulate
- poate utiliza: MySQL, PostgreSQL, SQLite

6. ● Bacula Monitor service
- administratorul sau userul poate urmari statusul serviciilor, a job-urilor
- poate anula, reprograma job-uri

8. Controlul Job-urilor
● Backup/restore centralizat
● Scheduler (inclusiv multiple job-uri simultan)
● Prioritizarea job-urilor

9. Securitate
● Verificarea integritatii fisierelor deja catalogate (similar cu Tripwire)
● Autentificare CRAM-MD5 intre servicii (implicit)
● Criptare comunicare intre servicii (TLS/SSL)
● Criptarea datelor de catre client
● MD5 sau SHA1 checksum pentru fisiere

10. Restaurare
● Restaurarea interactiva a unuia sau mai multor fisiere
● Restaurarea completa a unui sistem (bare metal)
● Restaurare chiar si atunci cand Catalogul nu e disponibil (cu bls si/sau
bextract)
● Restaurarea rapida a DB utilizand bootstrap file (contine o lista a
volumelor pe care s-a facut backup-ul)
● Recrearea catalogului utilizand bscan

11. SQL Catalog
● Baza de date ce contine
Volumes, Pools, Jobs si Files
salvate
● Support pentru MySQL,
PostgreSQL si SQLite
● Interogari SQL predefinite

12. Managementul volumelor
● Volumele pot fi etichetate pentru a preveni suprascrierea accidentala
● Mai multe joburi pot fi salvate pe un singur volum
● Formatul volumului e independent de client (datele clientilor Linux,
Solaris, Windows pot fi salvate in acelasi volume)
● Spool to disk – util pentru backup-uri Incrementale/Diferentiale ce sunt
salvate pe tape

13. Multiple Storage Device
● Autochanger (shell script pentru autoloader)
● Autochanger barcodes - tape labeling
● Suport pentru multiple autochanger magazines - utilizand barcodes sau
cititnd label-ul de pe tape
● Raw device backup/restore (Restore trebuie sa fie pe acelasi device)
● All Volume blocks (64K bytes) contin un checksum
● Migration support – datele se pot muta dintr-un pool/volume in altul
● Support pentru scrierea pe DVD

14. Multi-Operating System Support
● Compresie GZIP (file by file) la client
● Salvare si restor a POSIX ACLs si Extended Attributes
● Access control lists pentru acces la consola (useri isi acceseaza doar
datele proprii)
● Suport pentru save/restore a fisierelor mai mari de 2GB
● Support Unicode pentru numele fisierelor
● Backup consistent a fisierelor deschise din sistemele Windows cu
Volume Shadow Copy (VSS)

15. Director Resource Types
● Director – name, password, QueryFile, maximum concurrent jobs
● Job / JobDefs – backup, restore, verify; level, client, pool, RunScript
●
Schedule – 1st... 5th, sun... sat, w00 – w53, jan – dec, hourly - monthly
● FileSet – VSS, Include, Exclude, Options (GZIP, MD5, SHA1, onefs,
regex, acl)
● Client – name, password, retention period, priority
● Storage – name, password, device, Media Type (file, DAT, etc)
● Pool – type (backup, archive, copy, migration), Maximum Volume Bytes
● Catalog - DB Name
● Messages – destination, MailCommand
