Backup To DVD/CD/Flash protects you from losing all the irreplaceable information on your computer if something bad happens. It can quickly restore your valuable information if there is an accident or equipment failure, even if you lose your entire computer. To further protect you, Backup To DVD/CD/Flash allows you to check your backup discs at any time to make sure they are still restorable no matter how old they are or what might have happened to the backup discs since you made them. For further safety, you don't even need to have the backup program installed on a computer to restore from the backups--unless you choose otherwise, everything can be copied off the backup using Windows Explorer. This means you can still recover your data even if you have to replace your entire computer, and you've lost your download file to install Backup To DVD/CD/Flash from.
In addition to being safe, Backup To DVD/CD/Flash is also very flexible. It does multi-disc backups, splits and compresses big files, and makes incremental backups containing only recently modified files. It can also create a log file on your computer for each backup it does, with full details of what was saved to that backup. Backups can be fully automated and scheduled, so they're easy enough to do every day if you want. It can even synchronize the contents of selected folders between two computers, finding and copying changes made on one computer to the other. You choose what to back up by creating a Backup Plan, and using a simple Windows Explorer-like interface to select the folders and files you want to save. If you aren't sure what needs to be backed up on your computer, use our Wizard to create a Backup Plan for you by searching your entire computer for folders with the kinds of files you want to save. You don't have to remember where you put things. Backup Plans also adapt automatically when you create, delete, move or rename folders and files, so you don't have to remember to fix them after reorganizing your hard drive. Will make backups to DVD's, CD's, USB flash drives, and other USB connected storage devices.
