Back up ESXi VMs the right way: why free ESXi blocks most backup tools, how snapshot-based backups work, ghettoVCB and OVF export, and why snapshots aren't backups.
Fix a full Proxmox local-lvm: see why the thin pool fills, check usage with lvs and df, delete unused disks and snapshots, move storage, and stop it recurring.
Compare Proxmox storage options: LVM, LVM-Thin, and ZFS. How each handles thin provisioning, snapshots, RAM/ARC use, and performance, plus which to pick for your setup.
How VMware snapshots and delta disks really work, why they grow and slow your VMs, the 72-hour rule, and why a snapshot is not a backup. Practical guidance.
