GOLDEN RULE NO 1 – BACKUP
There is nothing that can replace backup to prevent data loss and avoid expensive recovery.
Backup simply means you are keeping at least one copy of the original data, preferably not in the same disk media. Backup could often be misconstrued as the followings:
I backup my notebook data in the external USB drive and then delete the original data in notebook.
I backup my data from the first partition to the second partition in the same physical disk.
Another pitfall is after backup, the backup data is never verified by the user until disaster strikes. Often, much to the horror of the user, the backup data was found to be corrupted, invalid or wrongly done.
If the data is important, store your backups at an off-site location. This helps to protect your backup from damage in case of a fire or disaster.
One practical problem while practicing backup is you need to stop work for such operation to take place. Often, this is not possible. The issue is often compounded by increasing data size, such as your ever-growing mailbox. Every backup operation could become a real pain if you have a busy schedule.
Whatever the situations, one fact remains – Diligent backup is a disciplinary act and the only way for you to circumvent data loss disaster.
