Frequently Asked Questions

Q: What is Déjà Vu?

A: Déjà Vu is a preference pane which allows you to schedule backups of important folders, or even your entire system.

It is also the strange feeling of having seen or experienced something before.

Q: What are the system requirements?

A: Mac OS X 10.2 or higher.

NOTE: You must have the BSD subsystem installed in order for Déjà Vu to work properly. This is part of a normal OS X installation. Also, Déjà Vu will only work with HFS+ (Mac OS Extended) formatted disks.

Q: How do I use Déjà Vu?

A: It's pretty simple:

• Click the lock and enter an Administrator password.

• Show Déjà Vu the folder(s) you wish to backup:

	When:
	How often the folder should be backed up (Daily, Weekly or Monthly).

	What:
	The folder you wish to backup; the source folder.

	Where:
	The folder where the files should be saved; the destination folder.

	Any folders which are unchecked will be ignored. This may be useful for those who frequently perform manual backups.

• Click 'Options' to set schedules and other backup options.

• Click the 'Schedule' button to schedule your backup. Your backup will not be scheduled unless you do this. If you make any changes within Déjà Vu, those changes will not take effect until you click the 'Schedule' button.

• To perform a manual backup, Option-click the 'Schedule' button and it will change to 'Backup'. Then click the 'Backup' button to perform your backup immediately. (The state of the 'Schedule/Backup' button will be preserved, so you can always use DV in "manual backup mode" if you prefer.)

• Once Déjà Vu has performed at least one backup, you will be able to view the most recent backup log by clicking the appropriate button near the top of the window.

Q: Do I have to be logged in for the backups to occur?

A: No, you don't have to be logged in. However, the backups will not take place if your machine is sleeping. You may want to change your Energy Saver preferences to prevent this from happening.

Q: Where can I backup my files?

A: Déjà Vu should be able to backup to any storage device which is mounted at the scheduled backup time. When backing up to a remote volume (WebDAV, AFP, NFS or SMB), you should select 'Remote backup' in the Options sheet. Remote backups will only be possible if root has write permissions on the remote volume. Déjà Vu first checks to see that all required disks are available, and that there's enough space on the destination disk to perform your backup.

Q: Are you responsible for any loss of data from using Déjà Vu?

A: No. You should not lose any data if you use Déjà Vu wisely. Try it out on a few test folders first and see how it works for you. Be especially careful when using the 'Mirror folder contents' option. Remember that in this case, any files in the backup destination folder which do not exist in the backup source folder will be deleted.

Q: How much does Déjà Vu cost?

A: It costs US$14.95. There is a trial period of 15 launches, during which time Déjà Vu will operate without any restrictions. When the trial period is over, Déjà Vu will be disabled until you register. A lot of work has gone into developing and improving Déjà Vu. Please support future development by registering your copy.
