©XSIBackup works at the ©ESXi hypervisor level and uses the built in ©ESXi cron service to schedule backup jobs. It is managed through an SSH session as root, just as you would manage any Linux server.

It has a minimum footprint on the server's resources yet offers close to hardware's theoretical limits at the time to backup data.

Our software has a built in block level deduplication engine. It can deduplicate data to any file system that you can mount over NFS or connect to over SSH. It needs nothing else to do it. It incorporates advanced indexing algorithms that allows it to find a block in a multi-terabyte VM in microseconds and does it at a sustained rate.

It uses little resources on your ©ESXi host, thus you can use it to backup your guest virtual machines while you use them without even noticing the load.

©XSIBackup is an extremely resilient piece of software, designed for professional system administrators that prefer reliable command line tools to fancy colourful windows. Our software is used by renowned enterprises and public institutions in five continents.

It offers features that differentiate it from all the other available solutions. It works both backing up data to local resources or over IP. This makes it the ideal tool to protect from new ©ESXi Ransomware, as you can keep your backup sets in some remote backup server authenticated through a private key, making it easier to protect and keeping backups in an isolated zone.

We offer a fully enabled trial version that you can use to try out all features until the trial period expires. Then you can still use it to backup virtual machines up to 60 GB in size to local datastores.

An nCurses GUI allows to quickly deploy backup and replication jobs as well as to test SMTP servers and run the jobs manually.
