I am asking the same question as this: How to list files that were changed in a certain range of time?
BUT. with a twist:
I have 10 folders with huge content(13Tb) and multiple folders with multiple level of subfolders within it. I would like to get for each folders , the changed file list for a certain period of time with decent performance ( returns within minutes instead of hours... )
example of a directory tree is as follows: Folder repository1 has 26 folder that is A - Z , each of the 26 folders has 26 folders as subfolders. This go till 100 more level like this. Each folder specified above has about >100 at least of images about 300kb - 1mb
In the end, we want to sync 2 systems in different data center with delta changes. We tried Rsync which it takes few hours to detect the changes and it is way over the SLA...
I am asking any linux command or file index with timestamp that I can query the changed file list within a time period. So that i can do Rsync the individual file over.
I am good too if you can suggest any open source tool for this job.
