Undelete Vmfs File [patched] ★ Secure & Safe

1. Introduction VMFS (Virtual Machine File System) is VMware's clustered file system used to store virtual machines (VMDKs, VMX, logs, etc.) on shared block storage (SAN, iSCSI, or local disks). Accidentally deleting a virtual machine file (e.g., a .vmdk or .vmx ) is a common administrative mistake.

sudo vmfs-undelete /dev/sdX1 /recovery_folder This scans for orphaned file entries. If you know the filename or extension: undelete vmfs file

dd if=/dev/sdX1 of=recovered.vmdk bs=512 skip=START_BLOCK count=BLOCKS This is tedious and only works for non-fragmented files. | Action | Purpose | |--------|---------| | Enable VMFS undelete (VMFS5/6 only) | esxcli storage vmfs undelete enable -l datastore1 | | Use snapshots + backups | Primary recovery method | | Set storage vMotion before deletions | Move critical VMs off datastore | | Configure trash can (NFS only) | Not native to VMFS | | Lower DeleteTimeout (advanced param) | Prevents accidental bulk deletes | Check if undelete is supported esxcli storage vmfs undelete status -l datastore_name If enabled, use: etc.) on shared block storage (SAN
