Class Notes

1. Types of Backup
   1. Full – backup everything
   2. Incremental – backup everything since the last incremental backup
   3. Differential – backup everything since the last Full backup
   4. Rsync – backup the bits that have changed in the files
   5. Combined – modern backup software uses a combination of techniques
2. Formats of Backup
   1. Compressed
   2. Bare Metal – allows you to recover not just files, but the entire operating system

   7. Offsite Backup is a good idea, but no one ever does it.
4. Software

   2. Server vs. Workstation – The software is different and the Server backup software costs around $600-$1000
   3. Add-ins – You may need special add-ins for your backup software to backup Microsoft SQL databases or Exchange servers.

   2. It can take a long time to backup or recover data
6. Final Thoughts
