Version 5.2.0 from 16/02/2012


 Important: In the current version, the option


 is deactivated by default. This means that the position of the files on the tape is not automatically tracked and stored in a file anymore.

 This option must be set manually in Z-DATdump versions 5.2 and higher. It can be set in the program settings or with the command-line parameter


 Unfortunately, the FastSeek option requires a lot of time on old tape drives which can lead to massive slowdowns when backing up more than 5,000 files.

 Users who back up only few but large files should still use this function because it makes restoring single files much faster and more comfortable because the tape drive can immediately reel the tape to the correct position instead of reading in the whole tape looking for the file.

 An index of the files on a tape used with Z-DATdump can also be created at a later time.

Version 5.0.0 from 16/9/2011


Major update with substantial improvements and optimizations.

 Z-DATdump was originally developed as an add-on module for our professional backup software Z-DBackup. Once installed, the program runs in the background for most users, without any user interaction.

 For our users who use Z-DATdump as a stand-alone application, we have updated the program interface and the user controls.

 In the manual selection for a tape dump, you can now select single files and/or several directories. If necessary, the selected data is split among multiple tapes (max. 10). It is important, however, that no single file exceeds the capacity of one tape.

Splitting very large files to multiple tapes will be implemented with one of the next updates.

 All Z-DATdump functions which use Windows Explorer were removed from the program and substituted with newly written routines. The user interface for file selections can be a little slower, but now even very large directory structures are displayed reliably.

 The current version contains adjustments for use on a Windows Server 2008 Core which does not usually have the normal Windows Explorer.

 In addition to the throughput-display in MB/s which refers to the time for the whole backup, the new version also displays the current tape speed during the backup and stores it in the log file.

 The new interface to Z-VSScopy makes it possible to back up files and directories from a volume shadow copy. The needed shadow copy is automatically created. Thus, open and locked files and applications can now be saved easily and reliably while they are running.

 The automatical CRC-check of the latest attached backup was improved. Z-DATdump's FastSeek feature is now also available for most Ultrium, LTO-3, LTO-4, and LTO-5 drives. This feature allows the user to quickly select single files from a backup and restore them. To use this feature, the backup must have been created with Z-DATdump 4.8 or newer.

 The backup size limitation of the Freeware Version of 4096 MB was increased to 12 GB which corresponds to the capacity of a DDS-3 tape.

Version 4.2.0


Major update with some improvements and optimizations. The update to version 4.0 is free and can be installed with the the LiveUpdate.

 For a new installation, however, a new registration key is needed, i.e. the registration data from version 3.xx cannot be used for an upgrade to version 4.0!


Improvements for use with Z-DBackup (Backup Software)

New commandline parameter for drive selection

Improved licensing system

Possibility to print and export the tape contents

Bugfix PowerSave Modus

Bugfix Use HD for filelist

Bugfix Infinite backup loop with defective files



Version 3.6.0


Minor update with some improvements and optimizations. Details of locked, exclusively opened and currently used files are no longer written to the tape and Z-DATdump skips the affected files. The tape backup is still marked as an error and an entry is created in the log file. With Z-OpenLock, Z-DATdump can be expanded to also backup any open and used files.



Version 3.2.0


Recognition of the tape hardware was improved.

 The configuration files of Z-DATdump were improved. This allows for using different tape drives. After the update, the program settings have to be reconfigured and saved.

If the option "Tape auto-format" is used, you should definitely prepare a new tape after the update to version 3.1!

 The new version now also supports the complete erasure of tapes using the hardware feature of the streamer (if present). The prompt/selection is done before deletion. Attention: the complete erasure can take 40-90 minutes depending on the medium!

 File list creation and the calculation of CRC check sums was improved.



Version 3.0.0


Major update with some improvements and optimizations. In the current version, backups can be continued, i.e. appended to an existing dump.

 The command line interface was improved and extended with several options. This allows for a better integration into pre-existing backup strategies including your own backup scripts. There are new commands for the restoration of single files and the output of tape information using the command-line.

 The file limit per dump can be increased from 384.000 to 2.000.000 in the professional version. To switch, deactivate the option "Create list of files in memory" in the program setup. If this option is deactivated, the list of files for backup is tempoprarily saved on the hard disk.

Note: The main field of application for Z-DATdump is the revision-safe archiving of backup-archives created with Z-DBackup, i.e. Z-DATdump is conceptually not a stand-alone backup software.
