## DESCRIPTION

**zbackup init** initializes a backup repository for the backup files to be stored.

**zbackup restore** restores the backup file to a tar file.

## OPTIONS

- \--threads number\_of\_threads

  Limit the partial LZMA compression to  *number\_of\_threads* needed. Recommended for 32-bit architectures.

- \--cache-size cache\_size\_in\_mb

  Use the cache size provided by *cache\_size\_in\_mb* to speed up the restoration process.
