http://www.ctera.com/home/next3.html Next3 File System Next3®: Enabling Thin Provisioned Snapshots CTERA has developed an open-source file system named Next3, based on the ubiquitous Ext3 file system, for the purpose of supporting enterprise-grade snapshot capabilities. Next3 provides the ability to create highly-efficient multiple snapshots that create restore points for the entire volume, with minimal impact on file system performance. The Next3 snapshots use dynamically allocated space, so there is no need to pre-allocate and waste valuable space on the disk for snapshots, and unused space is automatically recovered for file system use. Key Features * Dynamic allocation of disk space for snapshot use * Deleted snapshot space automatically recovered for file system use * Supports multiple snapshots with no deterioration in performance * Forward and backward compatible with Ext3 Serge |

I'd say put it on the list for 1.5, we really need to stop messing with 1.4 and release the official version (btw, I just uploaded RC4, still need to announce it) Heiko Quoting Serge Leschinsky <fi...@in...>: > http://www.ctera.com/home/next3.html > > > Next3 File System > Next3®: Enabling Thin Provisioned Snapshots > > CTERA has developed an open-source file system named Next3, based on the > ubiquitous Ext3 file system, for the purpose of supporting enterprise-grade > snapshot capabilities. > > Next3 provides the ability to create highly-efficient multiple snapshots that > create restore points for the entire volume, with minimal impact on > file system > performance.

Doesn't LVM do this? For any filesystem too. I'm not sure what the pros and cons of this approach are. I'd wait for some user demand. Dick -- Dick Middleton di...@fo... PGP Key ID: 0x9F9434FD |
