DoubleSafety - Data backup software

I backed up my files to my FTP server. How can I restore data from the backup copy?

Download the archive using a special program or Windows Explorer. After that, use DoubleSafety Restore Data wizard (see How to restore your data).

How does DoubleSafety process files opened by other programs?

DoubleSafety can back up files opened by other programs. However, for a file to be backed up, it must be available for reading.

What is the maximum size of data I can back up at a time?

Beginning from version 3.2, DoubleSafety uses the Zip64 technology. Due to this, the archive can be of any size.

Can I back up data without compressing them?

Yes, you can. You can set Compression quality to No compress in the Item Properties dialog box on the "Storage" tab. However, in this case data will not be compressed, but it still will be saved to a ZIP archive.

I open a created archive using Windows Explorer, but there is nothing in it although the size of the archive is correct. What's the matter?

Windows Explorer does not support archives created by DoubleSafety. It is recommended to use the DoubleSafety Restore Data wizard to restore data (see How to restore your data). You can also use such program as WinZip or WinRar.

In case of incremental backup, how does DoubleSafety find out that a file has been modified?

In case of incremental backup, DoubleSafety uses the Archive attribute to detect that the file has been modified. Once a file is created or modified, the system sets the Archive attribute for it. The Archive attribute is cleared only after the archive is successfully created.

Where does DoubleSafety store its settings?

All DoubleSafety settings, as well as its log, are stored in the folder C:\Documents and Settings\{username}\Application Data\DoubleSafety\. In case it is impossible to detect the Application Data folder (on systems with Internet Explorer 4.0 and earlier) the settings are stored in the program folder.

Can I back up data to my flash drive?

Yes, DoubleSafety works with flash drives the same as with usual local disks.

I back up data to a disk, the program ask if the disk should be erased each time. Can I avoid it?

To avoid it, you can choose to erase the disk using the "Erase media" drop-down menu in the Item Properties dialog box on the "Destination" tab.

I scheduled an item to be backed up automatically, but the process was not started. What's the matter?

Probably, DoubleSafety was not running at the moment when backup was due. Make sure DoubleSafety is launched at Windows startup (in the Settings dialog box).
