Creating a Custom Backup
12
Maintain archive
copies of files Under Options, select Keep Daily/Weekly/Monthly
archive.
This option maintains archive copies, even if the number
of backup copies has been exceeded. For example, if you
specify that DataKeeper maintain the last five versions of
a backup, and Keep daily/weekly/monthly archive is
selected, DataKeeper does the following:
• Saves the most recent five versions of the specified
files.
• Overwrites the five files in rotation, replacing the
oldest file each time.
• Saves up to seven daily, five weekly, and 12 monthly
archive copies in addition to the five most recent files.
• Does not create a daily, weekly, or monthly version of
files that have not changed since the last backup.
• Does not create a daily archive if the number of serial
backups has not been reached. For example, if you set
DataKeeper to maintain a history of five versions and
you only make four one day, DataKeeper does not
create an archived version for that day.
