Large incremental backups on NVMe drives

[SnakeSK]

Hello, this is an issue I have been scratching my head since 2.0, the problem we are expierencing is the client workstations with NVMe SSDs have a large backups (in the range of 2.0GB+ per day), limiting us from deploying veeam to our offsite workers. I am personally experiencing this on my mobile workstation with 2 NVMe drives:

Day1 (veeam 2.2) - 1.40 GB
Day2 (veeam 2.2) - 2.00 GB
Day3 (veeam 2.2) - 4.95 GB
Day4 (veeam 2.2) - 7.29 GB
Day5 (veeam 2.2) - 1.20 GB
Day6 (veeam 2.2) - 2.91 GB (cached)
Day7 (veeam 3.0) - 12.1. GB (cached)

Meanwhile our fileservers (with spinning HDDs) get about 300-500 megs per day, same story observed with our customers servers, I dont have SSD equipped server unfortunately. It seems pretty unreasonable to have 32GB of changed data per weekly use. I observed this even with light use (only outlook mails and system running) - next day, bam, 2 gigs of "changed data". I dont know how veeam calculates this but the backups are really huge for my liking on Windows Client OS.

Hello,
from my experience this has nothing to do with the storage technology (SSD / NVMe / HDD). 1-2GB changes seem to happen for each reboot of Windows. Which does not happen do your fileserver. That's why it has so small backups. Also Outlook creates a lot of changes.

Just to make sure: you do block based backup (volume level or entire computer)?

Best regards,
Hannes

Hello, yes that makes sense, it is entire computer backup
