Is anyone aware of a bare-metal disaster recovery backup solution that they have seen work with sles11 sp3 x86_64 with the following constraints:
- Secure boot enabled
- backup solution - full + incremental (not an imaging product)
- single server solution (not enterprise product)
- backup/restore to/from external usb disk

I had success with Clonezilla creating/restoring images to/from usb3 external disk - but unfortunately, this is an imaging product and does not offer what customers expect from a backup solution.

I am testing on HP ML350 and DL380 G9 server hardware and have tested the following without success:
Relax and Recover
Mondo Rescue
Active@ Disk Image
Acronis Trueimage Linux Server 11.5
Yosemite Server Backup
Microlite Backupedge
HP Data Protector
SEP - enterprise product not really suitable for single server - didn't test
