sys.backup - Vraćanje podataka

Za vraćanje pojedinačnih datoteka iz backupa koristi se program bconsole. Za vraćanje klijenta "od nule" vidjeti posebne upute.

Prvo je potrebno pokrenuti klijent bconsole (Bacula Console). Ukoliko se klijent uspješno spoji na backup servis pojavit će se sljedeće:

# bconsole

Enter a period to cancel a command.

Za vraćanje podataka koristi se naredba restore. Za vraćanje dijela datoteka treba odabrati treba odabrati opciju 5 ili 6, ovisno vraćaju li se podaci iz posljednjeg ili nekog starijeg backupa.

*restore  
Automatically selected Catalog: MyCatalog
Using Catalog "MyCatalog"

First you select one or more JobIds that contain files
to be restored. You will be presented several methods
of specifying the JobIds. Then you will be allowed to
select which files from those JobIds are to be restored.

To select the JobIds, you have the following choices:
     1: List last 20 Jobs run
     2: List Jobs where a given File is saved
     3: Enter list of comma separated JobIds to select
     4: Enter SQL list command
     5: Select the most recent backup for a client
     6: Select backup for a client before a specified time
     7: Enter a list of files to restore
     8: Enter a list of files to restore before a specified time
     9: Find the JobIds of the most recent backup for a client
    10: Find the JobIds for a backup for a client before a specified time
    11: Enter a list of directories to restore for found JobIds
    12: Select full restore to a specified Job date
    13: Cancel
Select item:  (1-13):

Ako je potrebno zatim se odabire klijent i skup datoteka (FileSet):

Select item:  (1-13): *5

You have selected the following JobIds: 134,141

Building directory tree for JobId(s) 134,141 ...  ++++++++++++++++++++++++++++++++++++++
37,447 files inserted into the tree.

You are now entering file selection mode where you add (mark) and
remove (unmark) files to be restored. No files are initially added, unless
you used the "all" keyword on the command line.
Enter "done" to leave this mode.

cwd is: /

Nakon toga potrebno je odabrati datoteke koje će se vratiti iz backupa. Za pregledavanje backupa koriste se naredbe cd i dir, te mark i unmark za odabir datoteka koje će se vratiti. Odabir datoteka završava se unosom naredbe done. U dolje navedenom primjeru smo selektirali jednu datoteku (dump mysql baze) koja se nalazi u /var/backups/bacula-cn, te kompletan sadžaj /etc/ssh direktorija.

$ *cd /var/backups/bacula-cn
cwd is: /var/backups/bacula-cn/
$ *mark mysql.dump.gz 
1 file marked.
$ *cd /etc
cwd is: /etc/
$ *mark ssh
9 files marked.
$ *done

Nakon toga još treba potvrditi vraćanje podataka:

OK to run? (yes/mod/no): *

Treba provjeriti da li su svi podaci ispravni i tek tada potvrditi sa yes. Ukoliko nešto treba mijenjati, koristiti mod. Obično je potrebno podesiti direktorij u koji će se podaci vratiti. Odabir / će vratiti stvari na originalno mjesto, no preporučamo koristiti neki novi privremeni direktorij (npr. /home/korisnik/restore) da vraćeni podaci nebi prepisali postojeće. Bitno je napomenuti da se vraćanjem podataka ne brišu podaci u odredišnom direktoriju, te se vraća cijela struktura direktorija (npr. vraćanjem datoteke /home/korisnik/datoteka.txt sa odredištem /home/korisnik/restore dobit će se datoteka /home/korisnik/restore/home/korisnik/datoteka.txt).
