env scm-backup

1. move to full nodename for /var/scm/backup/NODENAME (otherwise ‘’‘dayabay’‘’ clashes for Jimmy)
2. make tarball DNA mismatches get reported more loudly (maybe adopt into the fabric way of doing things)
   • Dev notes

slow trac due to backups

1. record backup time and rsync time, and make those graphically accessible : suspect slow Trac performance at ~13:30 is due to backups hogging CPU

The backup looks to have taked 40 min and rsync 50min

Repository Migration to shared services ?

• investigate how difficult to migrate Trac+SVN+TracWiki into git+github+Sphinx

  • especially needed for NTU hosted env, tracdev, heprez as need long term home that will survive me
  • aberdeen repository is fat : and cannot be open source ?

Alternatives to Git + Github

• http://en.wikipedia.org/wiki/Comparison_of_open_source_software_hosting_facilities
• https://bitbucket.org/ offers unlimited git or hg public and private repos, free for up to 5 users
