You’ll have to tweak the procedure in the section 1.2. Instead of removing the disk, you can simply add another disk to the VM where you want to restore the file. Once you do that, you have an additional drive (D: or E: depending on your config) available from where you can copy the neccessary files.
In case of Linux you may have to run fdisk –l , rescan the scsi bus using sysfs and mount the partition. After the copy you can unmount the partition.
Jump to section 1.4 in the document to clean up.
Hope this helps.
Re: Manually initiate a single file restore from an SMVI backup.
You still perform the same process for a single file restore you would do for a windows machine.
Once this is done, the clone has been created and attached to the VM you can just follow the below guide to mount the disks (NB. be careful mounting the servers cloned root disks on the same server). We have built a restore VM wwhere we do our single file VMs.
