You are right about the documentation. It should work the way you describe it.
When you do a FULL after the BASE, it should "examine" all the files and only backup those that have changed since the BASE (which they should be very few or none).
Can you show us your configuration files to verify you are not missing something?
As I understand it, the accurate backup requires the director to send all the file definitions of a previous backup to the client, for the client to decide what has changed.
That may take a while if the bandwidth is not there.
These are my job definitions config file for one of my servers:
Job {
Name = "server-base-fd-data"
JobDefs = "jobbaculadefs"
Client = server-fd
FileSet = "server-set"
Pool = Yearly
Level = Base
}
Job {
Name = "server-fd-data"
JobDefs = "jobbaculadefs"
Client = server-fd
Schedule = "IncWeeklyCycle"
FileSet = "server-set"
Client Run Before Job = "C:/windows/system32/ntbackup.exe backup systemstate /J \"vmbackup Backup\" /F \"C:\\SystemStateBackup.bkf\" /R:yes /L:f /SNAP:on"
Base = server-base-fd-data
Accurate = yes
}
What I do on my setup is I first run the BASE manually, then I run a manual FULL, then I just let the regular client schedule run the usual INCREMENTALS and DIFFERENTIALS (and FULLS).
I guess I am not using a "generic" BASE backup but a specific one per server.

Hello,
That would be strange if the 2 needs to be the same name or IP address as in the doc it is said that it can use backups from other clients as "template" of backup:
---------
extract of the doc:
A new Job directive Base=Jobx, Joby... permits to specify the list of files that will be used during Full backup as base.
Job {
Name = BackupLinux
Level= Base
...
}
Job {
Name = BackupZog4
Base = BackupZog4, BackupLinux
Accurate = yes
...
}
In this example, the job BackupZog4 will use the most recent version of all files contained in BackupZog4 and BackupLinux jobs. Base jobs should have run with level=Base to be used.
---------------------------------------------
Changing IP as you request would make me change the IP of the server too (WiFi and LAN are not in the same network), so first I would like to do more investigations without modifying IPs.
I will make some quick tests with small directories.
Could you post here the example of you base job and related job please ?
Thanks !
JC
