Planning your backups
It is advisable to communicate your backup plans to site
users so that they can plan their backup schedules.
Example. If you plan to schedule monthly backups for a site, intimating
the schedule to site users can help them plan for daily or weekly backups
A well-planned backup strategy should adequately address
Classify or prioritize
data in terms of criticality of operations
Set an operational value on your data assets to help
you establish an informed backup strategy for your data.
Ensure data consistency
Open or changing files can affect the consistency of
data being backed up. It is advisable to refrain from high activity on
the site being backed up to ensure data consistency. It is recommended
that the User Administrator be aware of your backup schedules to ensure
Choose an appropriate
An off-site or remote backup is recommended for data
that is critical to your operations.
Choose an appropriate
mode of transfer
You can choose the FTP or Download option to back up
your files. FTP is recommended as a more reliable and faster option. Large
backups to a remote server must be transferred using FTP, while small
files may be downloaded to a backup location.
Determine an appropriate
time to perform back ups
Take backups during a period of low activity. Changes
or revisions to data when a backup is in progress may corrupt
a backup. Also, changes done when a backup is in progress may not be backed
up. As a result, you can lose revisions that occur after the last back
These situations can be preempted
if site users are aware of your backup schedules and refrain from high
activity during backup.
Schedule backups to run regularly at an appointed time,
typically, when activity on the system is low. Scheduling backups frees
up your staff to attend to other tasks and also eliminates the need to
remember to back up the site manually. Frequency of changes is a good
indicator of how often a backup must be taken.
When backups are scheduled to run daily, weekly, or monthly, note that
data revisions made in the interim time-period [since the last backup]
will be lost if your system crashes or files get corrupted.
Determine the frequency
Ideally, critical files must be backed up daily; files
that can be replaced with minimal effort and loss of time can be backed
up weekly or monthly.
restores from the backup
After taking a backup, check the file size and perform
a dummy restore to ensure that the backup will restore successfully when
