A portable computer back up system copies user-selected files for back up as the computer is being used, and when the computer senses a network connection and the network is relatively available, the blocks of the files to be backed up are interleaved with, e.g., metadata and transmitted to a remote facility via the network. The back up system suspends the backing up of files if a disk space limit is reached, transmits any copied files when the network is available, deleting the back up copies of the files from disk, and then resumes copying files for back up. Also, each time the portable computer is connected to a network, it determines what other devices are on the network, and if the computer recognizes the network configuration, the computer reconfigures its settings as appropriate for, e.g., printing to the printer that happens to be connected to the particular network to which the portable computer is connected at the time.

[ What is claimed is:] [1.] A computer program product comprising:a computer program storage device readable by a digital processing system; andlogic means on the program storage device and including instructions executable by the digital processing system for performing method steps for backing up one or more blocks in at least one local computer file from at least one portable computer connectable to a computer network, the method steps performed by the computer program product comprising:preparing the blocks for back up;determining whether the portable computer is connected to a network;if the portable computer is connected to a network, permitting transmission of one or more of the blocks;interleaving the blocks with other data for transmission thereof;for at least some of the blocks in a local file to be backed up, copying two respective characters thereof defining respective first comparison values and generating respective digital signature codes defining second comparison values;for at least some of the blocks, periodically determining a test digital signature code and comparing it to the respective second comparison value; andwhen the test digital signature code of a block does not equal the respective second comparison value, determining whether the first two characters of the block equal one of the first comparison values.
