No company, however big, can survive catastrophic data loss if it has not prepared a data backup and recovery system. Just imagine a big business firm holding in its unprotected computers details of account receivables running into millions of pounds.
What will happen if all of the data was lost in a disaster when no backup was in place? That could be the end of the company, unless the numbers are on someone’s fingertips.
It is not possible to recreate the data without a proper backup plan having been conceived. A workable and practical Backup Plan involves using two tapes alternately, in order to safeguard the possibility of one tape getting defective. The tapes should be stored in a remote location away from the original business place.
In case of a business having a huge amount of data, it is not advisable to resort to daily backups. In this case full backups can be done on weekends and a ‘differential backup’ on a suitable working day. A differential backup saves all if the files that have been created or modified after the last FULL backup.
