Hi Community,
I have a challenge to find out what is causing my snapshots to grow so large. I have a vserver with different tenants and its used for different type of data mostly users home directories, but i haven't a deep knowledge of what kind of data the users are writing into it. I guess its like the typical filserver with all kinds of data , execpt backups and swapfiles.
The volume is 4TB cifs only , and we are doing timebased snapshots every 2 hour in business hours.
Suddenly last fall the snapshots expanded from approx 2-3GB to 30-40GB every 2 hour and its killing my space, as i have to maintan the snapshots for 1 month. (not all the hour , but daily and weekly)
So i need to find what data is new/changed every 2 hour , and i have tried using different tools - like treesize - to search for the data but i'm unable to pinpoint the bully.
Are there any way/method to kind of track the data in the separate snapshots to at least get a hint to where the data comes from ?
