zpaq is a journaling, incremental, deduplicating archiver for Windows
|
||
|
|
and Linux.
|
||
|
|
|
||
|
|
"Journaling" means that when you update a file or directory, both the
|
||
|
|
old and new versions are saved. You can extract from the archive as it
|
||
|
|
existed at any time in the past. "Incremental", means that when you back
|
||
|
|
up your entire hard drive, for example with:
|
||
|
|
|
||
|
|
zpaq -add e:backup.zpaq c:\*
|
||
|
|
|
||
|
|
only those files whose last-modified date has changed since the previous
|
||
|
|
backup are added. For 100 GB of files, this typically takes 1-2 minutes,
|
||
|
|
vs. a few hours to create the first version. "Deduplicating" means that
|
||
|
|
identical files or fragments are stored only once to save time and space.
