Volume copy service for Linux
Works like Volume Shadow Copy Service (VSS) for Windows. Windows administrators use VSS to take point in time snapshots, but before Hot Copy Linux administrators didn’t have an equivalent. We created Linux Hot Copy so every Linux server has a universal disk snapshot that is fast and easy to use.
Snapshots of any Linux Block Device
Linux Hot Copy creates an instant point-in-time volume snapshot of any block device while the system is running without interrupting applications.
No Dedicated Device or Storage
Unlike LVM, you don’t need dedicated Volume Group space to maintain the snapshot. Linux Hot Copy automatically uses free space on your block device for storage, enabling you to use it on any device. Or, specify an alternate device with more space to use as a changed block store.
High-Performance Volume Snapshots
Outperforms LVM snapshots. Linux Hot Copy has built-in file system awareness for Ext2/3/4 ReiserFS 3. It knows what parts of the block device are used by the file system and when you write to unused blocks on the disk it doesn’t perform a copy-on-write for these disk writes, enhancing performance.
Hot Copies are Readable AND Writable
Yes, you can read and even write to your snapshots. This opens up seemingly endless possibilities for use in system administration, allowing you to test scripts and programs on your data before running them on the live environment.
