What XSIBackup is
XSIBackup backs up and replicates virtual machines and host configuration on free or licensed VMware ESXi servers. It supports ESXi Free versions 5.5 through 8.0 and runs as an on-premises, self-hosted product on Linux. Backup methods include local and IP destinations, differential backups, replication, and cloud backup to SSH servers. Its block-level deduplication engine can write to filesystems mounted over NFS or connected through SSH. Recovery includes individual-file restores and unlimited restore points across the Free, Pro, and DC editions. The product comparison also lists Synology NAS compatibility when using the root user, plus XSIDirector compatibility for automated deployments. Remote backup servers can be authenticated with a private key, and backups can be certified using SHA-1. The Free plan allows local backups up to 100GB. Pro costs 89.00 USD once, while DC costs 169.00 USD once; licensed versions allow unlimited VM size. The maker describes the software as intended for professional system administrators who prefer command-line tools. 33HOPS is out of business and has not accepted new orders since July 15, 2024.
