First off, below is a list of Veeam file extensions with an explanation for each. I use this list for studying for various Veeam tests.
- VBK – this is a full backup file
- VIB – incremental backup file
- VRB – reverse incremental backup file
- (Quick note, I think VBR is a miss-print you may see on the web)
- VBM – replica metadata file
- BCO – configuration backup file
- DEM – private and public encryption key – Enterprise manager
- VSB – virtual synthetic backup (these are pointers to backup data blocks)
- VLB – Also, this is a database log
- DIT – active directory database file
- MDF – Microsoft SharePoint content database file
- EDB – Similarly, this is a Microsoft Exchange mailbox database
- ERM – Scale out backup repository
- RCT and MRT – used to complement CBT data with Microsoft Hyper-V 2016 RCT (Resilient Changed Tracking)
- CTP – info on data blocks that have changed for Hyper-V replication from a Veeam proprietary driver.
Overall, I found this information in my VMCE-95 textbook, and in Veeam’s online documentation.
Finally, this extension list is part of my Veeam Study Guide.
