Primocache w Macrium Ref w CBT
Posted: Fri May 17, 2019 7:47 am
Hi All,
Been reading the post from Jaga, BonzaiDuck and support re using PrimoCache with Macrium Reflect v7.
Here is my setup
older i7 6 core
64GB Ram
Samsung 860 Pro 512 GB C drive (Sata 3) - OS and Apps
Samsung 840 Pro 256 GB F drive (Sata 3) - Latest photos to edit and various caches and scratch disks
WD black 2TB Sata 2 D drive - general small files and older photos
WD black 4TB Sata 2 E drive - video source files
WD green 6TB Sata 2 G drive - backups
All partitions are 4kb cluster size apart from E video storage and this is 64kb.
My backups run Full at the start of the month then differentials for the rest of the month. These backups are for each drive C to F and reside on G. Macrium CBT is enabled, the blue running man on each drive I backup in the Macrium GUI. When a full backup is done there is a reference point to quickly do incremental or differentials using the Change Block Tracking data.
After installing Primo Cache the incremental and differentials take as long as the full backups and CBT is not being used. CBT init success is not on the Macrium log files.
I uninstalled Primo Cache and uninstalled / reinstalled Macrium and got the CBT working (diffs take 3 mins and full backups 3 hours). Reinstalled Primo Cache and setup some L1 and L2 caches (see below).
I then went into the Primo Cache Gui and paused the cache tasks and started a differential backup. Even though a differential is being performed the whole C/F/D drive is being read and not just changed files/blocks. I will check to see if it affects E the same - E does currently not have a cache task setup against it and a diff is running as I write this.
The cache setup is
C - 8GB L1 with no write defer and prefetch on / load at windows startup
D - 40GB L2 - L1 =0 (Level 2 cache is on the Pro 840 256GB SSD)
F - 4GB L1 with 10 second write defer / no prefetch / L2 = 0
It would seem that there is some clash between Primo and Macrium in terms of tracking changed data on each drive. Any one had experience of a similar setup?
Would really like to get primocache working with a good backup regime to add a bit more speed to my capable but getting a bit old now PC.
Thanks
