How to Backup Cadzow 2000
Cadzow 2000 supports two types of databases, Jet (Access .MDB) and SQL Server.
The method to back up these systems differs.
To determine which you are using:
Backing Up Cadzow 2000 Jet (.MDB) Databases
Cadzow 2000 includes a simple backup script (“BACKCAD”) which is designed to back up all the important components of your Cadzow 2000 installation. It creates a ZIP file on a logical drive of your choosing (A: C:, D:, E: etc) with the name YYYYMMDDn.zip. For example, if the date is 1st February 2005 the backup would be called 20050201A.ZIP. If another backup is done to the same drive it will be called 20050201B.ZIP and so on.
BACKCAD creates a sequence of backups which makes auditing, troubleshooting and disaster recovery easier, since each backup is not overwritten by the next. However, each individual backup file contains everything, so restoring is a matter of restoring the most recent backup file. It is not necessary to keep and restore all the previous backup files. The backups are not incremental.
Since BACKCAD writes to a logical drive letter, this can include floppy disks, hard disks, network drives, USB keys, ZIP drives, or indeed any logical volume accessible via a drive letter. However, this precludes tape drives and CD/DVD burners which are usually not writable via a drive letter and require special software.
A good backup strategy is to use multiple removable storage types. For example, you might do a daily backup to a ZIP drive, which allows the quick and easy use of the Cadzow 2000 backup utility, but store copies on a CD/DVD every month. This provides for a short-term backup media which can be recycled (expensive ZIP disks) and a long-term media which will be kept forever (cheap CDs). This helps protect your backup from drive and media failures which may not be detected until the media is tested.
Using BACKCAD — Cadzow 2000's Backup Routine
When finished, BACKCAD will tell you the filename the backup was saved to.
BACKCAD supports a number of options which can be invoked from the command line or from a shortcut.
If you launch Cadzow 2000 and receive the following message:
or if you attempt to run a backup and receive the following message:
… this usually means that another user is currently running a backup and you should wait for it to finish. However, if a previous backup was not completed properly, either because it was cancelled by the user, or there was a power failure, the “flag” set by the backup routine remains in place. In this case, run a backup, let it finish properly and the error will reset itself.
If that does not work, this may be cleared manually as follows:
Using a CD-Burner or Tape Drive

Backing Up Cadzow 2000 SQL Server Databases
Backing up a SQL Server database is typically performed by your network or database administrator.
