I have repository which contains multiple projects in the trunk folder. The requirement is to keep the latest 3 revisions in the repository of each projects and backup the remaining revisions. Example: "test1" application has revisions 1-10. I need to keep the revisions 10,9, and 8 (latest revisions) and backup the remaining revisions.(1-7).
"test2" application has revisions 11-16. I need to keep the revisions 16,15, and 14 (latest revisions) and backup the remaining revisions.(11-13). And so on...
As I am new to SVN, I'm quite unsure on how it could be done. Can someone please help on how it can be done. Thanks in advance.
