Hello, in CBT page I can read “Change block tracking for UrBackup Client on Windows speeds up image and file backups…”, so I bought a license to test CBT in my home laptop.
For my computer I only do file backups, selecting the folders I want to save, and no image backup is done.
I have “Block differences - hashed” in transfer mode, for local and Internet backups.
In file backups, previous to CBT installing, I see that a hashing is calculated in first full backup for all files in my backup (72GB), and when differential backup is done, the hashing is calculated again, and only the diferences are sent and a patch with size of differences is applied to previous version files on server:
Example:

04/08/22 01:48 INFO Time taken for backing up client AudiPC066: 10m 10s
After installing CBT Client, restarting the computer, I verified that driver is active for my drives:
|Informativos|04/08/22 01:40|Change block tracking active on volume E:|
|Informativos|04/08/22 01:40|Scanning for changed hard links on volume of “E:”…|
But I see no difference in incremental file backup with CBT: the indexing continues doing a hashing for all files, it sends the differences, and it takes nearly the same time… may I be missing something? Is CBT working fine for file backups, not only image backups??
Thanks.
