ATIH 2012 Plus Pack and SSD Caching

Thread needs solution

Bonjour,

j'utilise le disque de secours créé par Acronis WinPE IsoBuilder (Plus Pack 2012 build 6154) pour sauvegarder ou restaurer ma partition système.
Le problème est le suivant: le disque dur système (en mode RAID) et le disque SSD utilisé en caching n'apparaissent absolument pas si le SSD caching est activé par Intel SRT. On ne peut donc pas faire de sauvegarde ou restauration dans ces conditions.

Pour contourner le problème il faut à chaque opération désactiver le SSD caching.

Pourquoi cette incompatibilité? Est-ce normal?

Configuration PC:
Carte mère ASUS P8Z68 Deluxe GEN3
Core I7 2600K
SSD Crucial M4 64Go used as SSD caching
HDD WD Caviar black 1To used for system + applications

It is not a surprise that the WinPE environment doesn't support disk caching. Maybe you can do your backups in Windows?
The thing that I don't know is how a restore:
- will preserve the integrity of the cache and cached disk information relationship,
- intel RST will pick up the cache management after a disk and partition restore.

It is tempting to say you should backup and restore the cache and the cached disk at the same time, but you might have to restore all disks at the same time, as I suspect that some management information is on the system disk as well.

Something to try. For the experimentation:
- you do a backup of your entire system withou the cache enabled, as a precaution,
- you do a backup with the caching enabled in Windows, and you make sure you include all the partitions of the SSD and the partitions/disks being cached.
- THen try different restore scenarios and see how the caching mechanism and data integrity works out.
