What would be a complete bare metal restore from backup when using PBS as backup solution?

I know at this time the Linux client is complete, for Windows there are partial clients, some discussed in the forum.

Having read through much of the docs and other info on the net, I understood a lot of info about VM restore, file(s) restore, but nothing yet (as in a top to bottom how-to) on how to properly do a backup on a bare-metal system and perform a restore later, starting from same bare-metal (ie no OS on it).

Thank you.
 
Hi,

you can do a backups by using PBS client.
The bare-metal recovery is not provided from the box yet.
You could manually restore partitions/files, reinstall the bootloader, and recover configs.
For bare-metal recovery needed third-party boot media plus extracted backups.
 
Regarding Linux I could imagine 2 bare-metal scenarios:

1) attempting most through PBS client:
- disk layout, partitioning, boot related stuff, /dev - saved separately
- effectively everything (ie except /dev, /proc /sys and the like) backuped up, though I would set different jobs for system files and data files
- have a linux based live cd / usb which includes the client (probably the statically linked) and some scripts to restore the initial layout, then calling PBS client to restore all files

2) focus only on data files, maybe configs through PBS client:
- have OS installation as a separate manual step, or have a bare-metal starting point image to deploy more directly.
- have necessary packages and updates listed in the restore procedure and do them manually or through custom script
- restore config through PBS client, with all relevant services stopped
- restore data files through PBS client

I have done type 2) restores using initial image and a copy of the files via rsync on another storage. Of course, without things such as versioning as supported by PBS.

However, given sensibilities of Windows Server and the early state of exising PBS clients, I am lost as for a scenario for it.
