A backup method, suitable for a computer system including a hard disk and at least one recovery point stored therein, said recovery points holding data being changed within said hard disk, said backup method comprising the steps of:
- selecting a predetermined recovery point;
- writing data contained in a base recovery point into a external storage media, said base recovery point corresponding to a status of said hard disk;
- and
- writing data contained in said predetermined recovery point into said external storage media.
A backup method, suitable for a computer system including a hard disk and a plurality of recovery points stored therein, said recovery points holding data being changed within said hard disk, said backup method comprising the steps of:
- selecting at least one recovery point;
- determining a recovery point among said at least one recovery point in accordance with creating time of said at least one recovery point;
- writing data contained in a base recovery point into a external storage media, said base recovery point corresponding to a status of said hard disk;
- and
- writing data contained in said determined recovery point and a predetermined number of intermediate recovery points between said base recovery point and said determined recovery point, into said external storage media.
A backup method, suitable for a computer system including a hard disk and a first predetermined number of recovery points stored therein, said first predetermined number of recovery points holding data being changed within said hard disk, said backup method comprising the steps of:
- selecting at least one recovery point among said first predetermined number of recovery points;
- determining a recovery point among said at least one recovery point in accordance with creating time of said at least one recovery point;
- and
- writing data contained in said determined recovery point and a second predetermined number of time-relevant recovery points among said first predetermined number of recovery points, into said external storage media.
