No storage vendor can guarantee an absolute data integrity. It doesn’t affect your ability to perform file level restores from your Veeam Backup & Replication console. In case you don’t use the Enterprise Manager, then you can cut some (sometimes significant) time off your backup window and save space on the C: drive of a Veeam server by disabling this option. With “ VM Guest File System Indexing” enabled, Veeam Backup & Replication creates a catalog of files inside the VM, allowing you to use guest file search and perform 1-click restores through our Veeam Backup Enterprise Manager.

In Applications menu, you can specify options for various application or disable guest processing completely for a VM VM guest file system indexing

However, if you use it as a main backup method, it would produce a very specific backup chain consisting of a full backup file and a mix of forward and reverse incremental restore points.įigure 4. For example, it will help you transform your current chain into the reverse incremental one for archival purposes. Keep in mind though that this option starts a task of transforming incremental backups (.VIB) into rollbacks (.VRB), which is very laborious for your target backup repository. When you set up a synthetic full backup mode, there is an additional “ Transform previous backup chains into rollbacks” option available. However, not every storage type provides a good performance with synthetic operations, so we advise to use active full backup as an alternative. Synthetic full operation builds a full backup file from the restore points already residing in your repository. This allows for faster restores in case the most recent point is used, but the difference is often negligible in comparison to a forward incremental chain (if its length is not unreasonably long, we usually suggest it to be around 30 days). With the reverse incremental backup, you get a full backup as the last point in the chain. Depending on the type of storage in use, it can be three or more times slower than other modes.

Reverse incremental backup method is our oldest backup method and consequently the slowest. Forward incremental requires more space, but is also more robust (because a backup chain is further divided in subchains by periodic full backup). Forever forward incremental (no periodic full backup) requires less space and offers decent performance. In most cases, forward incremental or forever forward incremental backup modes are recommended as the fastest ones. It includes some basic advice on the initial setup, and outlines the most common misconfigurations that we, at Veeam Support, find in clients’ infrastructures during our investigations. This article is aimed at giving you a smooth start with Veeam Backup & Replication.
