- 1. Support for Windows XP
- =========================
- DataKeeper 5.0 is supported under Windows XP.
-
-
- 2. Known Issues
- ===============
- a. To install DataKeeper under Windows NT, Windows 2000, or
- Windows XP, you must have administrator privileges.
-
- b. "Permission denied" errors may occur if you try to restore
- files to their original location when the original file exists
- and is open. Windows system files are often open and beyond
- your control.
-
- c. The directory tree will collapse back to the root directory
- when refreshing the list if you do not have the last folder in
- the expanded tree highlighted.
-
- d. Datakeeper can be uninstalled as you would uninstall other
- programs. However, the uninstall process leaves all the backup
- specification files (.DKS) and log files. To remove them,
- complete a search by typing "*.DKS" in the Named text box.
- When you remove DataKeeper, you can delete those files (they
- are large and occupy a lot of space). If you use multiple
- primary and substitute backup locations, they may contain
- obsolete backup files that you may want to delete to reclaim
- disk space.
-
-
- 3. Interaction with other programs
- ==================================
- To prevent performance degradation of your system when
- monitoring, DataKeeper does two things:
-
- Delay write -- When a file is modified, DataKeeper delays
- making a backup for five seconds. This prevents hard disk
- "thrashing" caused by applications that write groups of data
- to a file with many short pauses between them. If DataKeeper
- tried to copy the file immediately after every write, the copy
- would be in progress during the next write and the copying
- process would have to start over.
-
- File system load monitoring -- To avoid slowing down your
- system, DataKeeper monitors file system activity and waits for
- periods of inactivity to back up files. Simultaneously running
- programs that continuously scan the disk may cause DataKeeper
- to delay copying files for an excessive length of time.
-
- If you notice hard disk thrashing or suspect that an extended
- delayed write situation exists, you can stop monitoring in
- DataKeeper and it will report the number of files that are
- waiting to be backed up (if any). If you consistently have a
- large number of files waiting to be backed up, especially when
- Windows is shutting down, try to determine what applications
- (such as disk optimizing tools and virus scanners) are
- conflicting with DataKeeper. You should consider scheduling
- them to run when you are not actively using the system.
