CRU Frequently Asked Questions

CRU is at its End Of Life and TOLIS Group no longer supports or develops this technology. While you may use CRU for your crash recovery model, users looking for a crash recovery tool on Linux are suggested to use Mondo Rescue or Clonezilla .

I use the new ext3 journaling filesystem. Does CRU support this filesystem type?
Starting with CRU 2.4.6, CRU provides full support for ext3 journaling filesystems.

Previous versions of CRU only support the LILO boot loader. Newer Linux distributions now offer GRUB as their default boot loader. Does CRU suppoprt GRUB systems?
Starting with CRU 2.4.6, CRU provides support for both LILO and GRUB boot loaders.

When I run CRU, I receive an error that states "CRU requires BRU 15.1 or later for proper operation."
You must have BRU 15.1 or later to use CRU. If you have a current version of BRU and still get this error, try this:

$ cp /bru/bru.static /bru/bru_cru.dyn5
 

CRU doesn't do all I need.
CRU was written to work for the majority of BRU users on the major Linux distributions. If you find that CRU does not do what you need, you can change it. CRU is open source, licensed under the QPL, which allows you to make changes to suit your needs. You can submit the changes you've made to cru_updates [at] tolisgroup.com

Why Didn't CRU Work On My System?
CRU is an open source product that was designed to automatically recognize most system configurations; however, it is highly probably that there is a configuration or two out there that CRU will not automatically recognize.
