This page is for discussing ideas regarding next-generation (NG) imaging tools.
+
{{expand}}
  
Note that some of the ideas mentioned can be already used by imaging tools, but the idea of this page is to determine how useful these features could be for next-generation of imaging tools.
+
== External Links ==
The scope is mainly a software-based imaging tools, but not limited to. Some features might not be doable, because of limitations of certain image file formats.
+
  
Please, do not delete text (ideas) here, use the discussion page if you want to discuss the usefulness of a feature.

* Compression

* User suspend/resume, resume after failure

* Remote imaging

* Error resistance in reading storage media, e.d. disks

** maybe have different techniques, e.g. to use for heavily damaged storage media
+
* Support different types of storage media
+
** disk
+
** volume
+
** optical discs
+
** memory
+
** files and directories
+
* Store relevant data about the storage media and the imaging process
+
** read errors
+
* Support multiple image format
+
** not all image formats have support for all the features

+
== Compression ==
+
* Reduces the amount of data that needs to be written; improved the overall imaging speed.
+
** hash-based imaging
+
** detection of easy (emtpy-block) and hard (encrypted block) to compress data
+
** multi-threaded compression
+
** sparse ranges
+
** de-duplication
