Saving Your Data
Your data is preserved in the repositories.
You should regularly perform backups of your repository to avoid loss of your data due to unforeseen circumstances such as hard disk failure.
You should keep these backups in a safe location, on a different site from that containing the data.
Backup frequency will vary depending on how quickly the data changes. Weekly backups are generally sufficient when one user is involved. Backups should be more frequent when multiple users are working every day. You should back up your repository before and after important modifications are made to it.

Remember to regularly back up your data and to keep several backups.
