- poate utiliza: MySQL, PostgreSQL, SQLite

● Bacula Monitor service

- administratorul sau userul poate urmari statusul serviciilor, a job-urilor

- poate anula, reprograma job-uri

Controlul Job-urilor

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

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

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

● Baza de date ce contine Volumes, Pools, Jobs si Files salvate

● Support pentru MySQL, PostgreSQL si SQLite

● Interogari SQL predefinite

SQL Catalog

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

Multiple Storage Device

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

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)

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
