What can prevent backups?
I've got a bunch of machines (10.4, 10.5, iMacs, MacBooks, etc) that are _supposed_ to be running SD! every night and backing up to a sparseimage on a network share. They don't always run, and while some of it might be operator error (if the machine is powered off or the laptop is sleeping, I can't really expect it to work), some of it seems to be related to apps that are running.
Is there a list of known apps that will prevent SD! from running at a scheduled time? I'm guessing VMWare Fusion, but I can't be sure... Some of my users have dozens of apps open, what are the ramifications of open files and open apps on SD! backups (and the restoration of the resulting files after a hard disk crash)? I've set their machines up to: Log in the user without a password (some really hate this) Never sleep (when connected to power cord) Mount the backup share when they log in. I've instructed them to: Reboot the machine when they are done with it for the night. Ensure the power cable and network cable are attached. Just walk away. [This is really difficult for some of my users, and doesn't always happen.] Any thoughts? Anything I can remove or change above to make it easier on the users but still make a useful (recoverable) backup? How does SD! deal with open files and apps when it does it's backup? Should/does SD! work over wireless networks flawlessly? Great program, though, once we get the above details worked out we'll be golden! |
Running applications wouldn't prevent SD! from running, but might prevent that application's files from being copied properly. VMWare is a good example: you want to have big data files, like that, written to disk and closed before they're copied.
SD! should work fine -- although slowly -- over wireless... |
