How do I freeze Vista backup on WHS before upgrading to Windows 7 RRS feed

    Since WHS backs up incrementally, how do I freeze the Vista backup and begin anew after 'upgrading' a computer to Windows 7?  I may want to return to Vista as it was prior to upgrade.  Do I have to do a Manual Backup, and if so does it really backup everything again or is it incremental?  Similarly when WHS automatically deletes older backups how does it capture the incremental information on that backup if nothing changed since then, i.e. it never gets backed up again?  In other words...how does WHS backkup really work?

    Every backup is a full backup, as far as restoring is concerned.

    As for which backups to retain, delete, etc. that's up to you, but if you delete a backup, you lose access to it and to the specific file versions it contains. So if you do a backup on Monday, then change a document Tuesday and do another backup, then delete the Monday backup, you lose access to the version of the document prior to the Tuesday changes.

    Is that any help? :)

    Choose a recent backup and flag it as kept. You'll find this documented in the Console help, on the page titled Learn more about backup management.

    If you do a manual backup right before the upgrade, the backup will be kept until you delete it (default setting for manual backups). When you do the manual backup, name it something like "vista before upgrade to win 7" so you remember why you kept it.

    Thanks Ken.  I've read the help, again, but it doesn't explain about incremental backups.  Is EACH of the daily backups a full backup rather than an incremental backup?  Perhaps that is what I am missing.  Obviously then keeping the last backup or a new manual one will be a complete backup of everything.  Does this mean that I can delete ALL the prior backups except the last one and have ALL the data?
