Do any of these circumstances sound familiar?
If so, ProjectLocker Backup Subscriptions can help. Backup Subscriptions let you automatically archive your project(s) with a frequency of your choice (monthly, weekly, or daily).
You set it up once, and then the archives are automatically created for you on the schedule you choose. Each archive contains the source repository for the project(s) (Git or Subversion), as well as the Trac data for the project.
And the data stored in the archives is 100% portable so that you can even restore to an in-house server if you choose.
