Keep backups: Specifies how long you want the backups to be stored in the archive. A term can

be set in hours, days, weeks, months, or years. For monthly backups, you can

al so sel ect Keep indefinitely if you want them to b e saved forever.

The default values for each backup type are as follows.

Daily: 7 days (recommended minimum)

Weekl y: 4 weeks

Monthly: indefinitely

The retention period for weekly backups must exceed that for daily backups; the

monthly backups' retention period must be gr eater than the weekly backups'

reten ti on peri od.

We recommend s etti ng a reten ti on peri od of at l eas t one week for dail y

backups.

At all times, a backup is not deleted until all backups that directly depend on it become subject to deletion as

well. This is why you might see a weekly or a monthly backup remain in the archive for a few days past its

expected expiration date.

If the schedule starts with a daily or a weekly backup, a full backup is created instead.

Examples

Each day of the past week, each week of the past month

Let us consider a GFS backup scheme that many may find useful.

 Back up files every day, including weekends

 Be able to recover files as of any date over the past seven days

 Have access to weekly backups of the past month

 Keep monthly backups indefinitely.

Backup scheme parameters can then be set up as follows.

 Start backup at: 11:00 PM

 Back up on: All days

 Weekly/monthly: Saturday ( for e x ampl e)

 Keep backups:

 Daily: 1 week

 Weekly: 1 month

 Monthly: indefinitely

As a result, an archive of daily, weekly, and monthly backups will be created. Daily backups will be

available for seven days since creation. For instance, a daily backup of Sunday, January 1, will be

available through next Sunday, January 8; the first weekly backup, the one of Saturday, January 7,

will be stored on the system until February 7. Monthly backups will never be deleted.

Limited storage

If you do not want to arrange a vast amount of space to store a huge archive, you may set up a GFS

scheme so as to make your backups more short-lived, at the same time ensuring that your

information can be recovered in case of an accidental data loss.

Suppose that you need to:

 Perform backups at the end of each working day
