Abstract

An embodiment of the invention provides a backup method for a portable device to back up a first data to a backup server. The backup method includes steps of determining whether the backup server can be accessed; when the backup server can be accessed, establishing a first data transmission path that the first data would be backed up to the backup server via a third party, a second data transmission path that the first data would be backed up to the backup server via a router, and a third data transmission path that the first data would directly backed up to the backup server; selecting one data transmission path among the first, second and third data transmission paths; and backing up the first data via the selected data transmission path.

Claims

1. A backup method for a portable device to back up a first data to a backup server, comprising:

determining whether the backup server can be accessed;

when the backup server can be accessed, establishing a first data transmission path that the first data would be backed up to the backup server via a third party, a second data transmission path that the first data would be backed up to the backup server via a router, and a third data transmission path that the first data would directly backed up to the backup server;

selecting one data transmission path among the first, second and third data transmission paths according to a parameter; and

backing up the first data via the selected data transmission path.

2. The method as claimed in claim 1, further comprising:

when the backup server cannot be accessed, establishing only the first data transmission path and transmitting and storing the first data to a third party.

3. The method as claimed in claim 2, wherein after the first data is stored in the third party, the third party detects whether the backup server can be accessed, and when the backup server can be accessed by the third party, the third party transmits and stores the first data to the backup server.

4. The method as claimed in claim 1, wherein the parameter is a network link quality or a transmission speed.

5. The method as claimed in claim 1, wherein when the portable device and the backup server are in a first network and the third party is in a second network, the first data is backed up to the backup server via the second data transmission path or the third data transmission path.

6. A portable device, comprising:

a backup program; and

a processor, wherein when the backup program is executed by the processor, the processor first determines whether the backup server can be accessed, when the backup server can be accessed, the processor establishes a first data transmission path that the first data would be backed up to the backup server via a third party, a second data transmission path that the first data would be backed up to the backup server via a router, and a third data transmission path that the first data would directly backed up to the backup server, the processor then selects one data transmission path among the first, second and third data transmission paths according to a parameter, and the processor transmits and stores the first data to the backup server via the selected data transmission path.

7. The portable device as claimed in claim 6, wherein when the backup server cannot be accessed, the processor establishes only the first data transmission path and transmitting and storing the first data to a third party.

8. The portable device as claimed in claim 7, wherein after the first data is stored in the third party, the third party detects whether the backup server can be accessed, and when the backup server can be accessed by the third party, the third party transmits and stores the first data to the backup server.

9. The portable device as claimed in claim 6, wherein the parameter is a network link quality or a transmission speed.

10. The portable device as claimed in claim 6, wherein when the portable device and the backup server are in a first network and the third party is in a second network, the first data is backed up to the backup server via the second data transmission path or the third data transmission path.
