External drives and network mapped drives can be used with ZCB for storage of backup data.

Also, ZCB can take backups of data on an external or network mapped drive, including a Linux machine using SMB or NFS shares.

External drives

You can use external drives just like your local drives. No configuration is needed.

Mapped drives and the amandabackup user

Most ZCB functions are performed by the amandabackup user.  Backups of mapped drives are no different; amandabackup must exist on the remote machine and should have sufficient permissions to access the mapped drive remotely.

Please see What is the amandabackup user? for more details about amandabackup.

Create amandabackup on the remote network machine

If your machine is not part of a Windows Domain

If your machine is part of a Windows Domain

By default, amandabackup is created as a local user. To access network shares in a domain, amandabackup must be a domain user. Once you do this, future installations of ZCB on the network will use this domain user.

Map the network drive

Map the drive on ZCB machine with the credentials of amandabackup user:

Limitations for backups of data stored on mapped network drives

ZCB uses the Volume Shadow Copy Service (VSS) snapshots to perform backups of locked, in-use, and system files. However, VSS is only available for use on local drives.

Network drives will not be backed up using VSS. Locked, in-use, and system files will not be backed up. A warning will appear on the ZCB Report page if any files are skipped during the backup.

An exact listing of skipped files will be in the <ZCB Install Directory>\Debug\BackupErrors*.txt files.
