I'm having a hard time getting used to wbadmin, as I come from a NTbackup background.
I have this situation: One Windows 2008 R2 server, with roles Active Directory, file server, print server, DNS server and DHCP server. Operating system is on C: (total size 100 GB, 60 GB used) and file server's data is on E: (total size 380 GB, 300 GB used).
We have bought two external USB hard disks, each of 2 TB, labelled "USB-A" and "USB-B". Both "USB-A" and "USB-B" are never plugged at the same time to the server. Both "USB-A" and "USB-B" have been assigned the "K:" volume letter. All this works fine.
What we want: daily backups for week-1 to USB-A, daily backups for week-2 to USB-B, daily backups for week-3 to USB-A, daily backups for week-4 to USB-B, daily backups for week-5 to USB-A, and so on...
I run this command daily at 21:05 h. from the Windows server task scheduler:
wbadmin start backup -backupTarget:K: -include:C:,E: -exclude:"E:\$RECYCLE.BIN","E:\System Volume Information","E:\programs","E:\Users\TestUser","C:\TEMP" -vssfull -allCritical -systemState -quiet >> C:\TEMP\backuplog.txt
(Ok, I know it is redundant to say at the same time -allCritial with -include:C: and -systemstate, but lets put that aside for now.)
The problem: when on Monday, we want the backup to "start fresh", i.e. to make a full backup from scratch, discarding whatever old backups may be in the K: volume. What it happens on Monday is that the wbadmin program does an "incremental backup" over the last backup from the Friday nine days before. We do not want this (plus it takes almost 20 hours to finish, whereas a full backup from scratch only takes about 6 hours). Essentially, we want every Monday to make a full backup from scratch on K:, but we don't know how to force wbadmin to do so.
Any help, please?
