Backups are a very important point of maintaining the customer’s installation. Below is an article explaining the extra options found in Vault Collaboration and Vault Manufacturing.
The subject of Backup is something often talked about as the central part of maintaining a working Vault installation. But some recent experiences highlight the need to repeat it again. A customer claimed to have a backup – but found that the routine was not working and they were running on a server where the hard disk was starting to fail. They managed to get the data moved to another server with minimal file loss – but could have lost everything. So the lesson learned is – check up on Vault Backups, and do not always take Yes for answer when asking if backup is running. Check for existence and preferably try to restore the backup on another test machine. It will save time and make everybody sleep more relaxed!
With Vault Collaboration and Manufacturing 2010 we have Hot (a.k.a. Live) and Incremental Backup. Hot backup runs in the background while the ADMS is still operational, handy in a multi-site setup with different time active zones. The result is a regular backup with a full DB and File store, which can be restored directly.
Incremental backup consists of first a full backup and then incremental backups with the full DB, but only the difference (files added or deleted) of the file store. This means a much faster backup and smaller data package to manage. When restoring an incremental backup, all the _IncXX backup data sets back to the last full backup needs to be accessible and left in a structure with all folders on the same level. When restoring you just need to point to the LAST _IncXX backup folder and it will find the history back to the full backup, and restore the database in its entirety.
