Created the page, saw it linked from PostgreSQL and felt some clarification might need to be made for some people who aren't familiar with this. grrowl 04:12, 31 March 2006 (UTC)

Article Very Wrong
Point-in-time recovery means you can recover from any point in time since the last backup. This article suggests that Windows XP has this ability, I assume the author is talking about the System Restore feature. If you have a restore point from last week, you can only restore your system to the state it was in last week. You could not for instance restore to yesterday. Therefore System Restore is not an example of Point-in-time recovery. --138.80.0.10 (talk) 01:51, 7 April 2010 (UTC)

Point-in-time (PIT) rollback works like an undo would in a document except here file and registry changes are undoable.

While initializing a PIT the disk of interest makes a copy of the tree tables.

Then as changes are made throughout the disk space they are recorded in that one particular PIT file space.

Changes made to each disk block are "Stacked". To rollback to some previous time the changes are unstacked and undone.

The advantage here should be only changes are stored this enables the host to continue in real time.

This is a lighter task than overwriting a whole file for each change.

This PIT / Undo process is useful for across the network backups and replications.
