CXARC is a data archive tool that will pack large numbers of files into as small a space as possible for easier uploading, quicker copying and greater storage capacity.

CXARC archives are designed to make highly efficient use of a normal broadband Internet connection in backing up data to a remote Internet based file store.

CXARC is also useful for squeezing more storage space out of a recordable CD, DVD or Blu-Ray disk or flash memory key.



CXARC will:

  • Compress large amounts of storage without data loss to use less space and be faster to upload or copy.
  • De-duplicate files so if the same file appears more than once it is only stored once in the archive. On archive extraction all original copies are recreated. Even parts of a file may be de-duplicated.
  • Group many small files together into fewer, larger blocks for efficient network usage and performance.
  • Check file integrity with a checksum to ensure no corruption could have occured between storage and recovery

We also have an advanced version, CXARC Pro, that adds the ability to snapshot archives and extract multiple file versions, please contact us for more details.

CXARC currently requires a Unix/Linux like environment and is a Perl utility.
