The resulting archive: ideal
Assume you select to keep daily backups for 7 days, weekly backups for 2 weeks and monthly
backups for 6 months. Here is how your archive would appear after the backup plan is launched if all
the backups were full and so could be deleted as soon as the scheme requires.
The left column shows days of the week. For each day of the week, the content of the archive after
the regular backup and the subsequent cleanup is shown.
“D” stands for the backup that is considered Daily. “W” stands for the backup that is considered
Weekly. “M” stands for the backup that is considered Monthly.
An ideal archive created according to the GFS scheme.
Schedule: Workdays at 8:00 PM
Weekly/Monthly: Friday
Keep daily backups: 7 days
Keep weekly backups: 2 weeks
Keep monthly backups: 6 months
Starting from the third week, weekly backups will be regularly deleted. After 6 months, monthly
backups will start to be deleted. The diagram for weekly and monthly backups will look similar to the
week-based timescale.
The resulting archive: real
In reality, the archive content will somewhat differ from the ideal scheme.
