Backup operations on selected directories are performed in a computing system. File system operations that impact the ability to backup the selected directories are failed while other file system operations are allowed. In particular, file system operations that would require a trawl of the selected directory in order to perform the backup operation are failed.

Directory selective backups

A system of terminating signals in a telecommunication system is disclosed. In one embodiment a line card comprises functional circuitry, line card connector contacts and a termination resistor. The functional circuitry is used to interface first type ports with second type ports. The line card connector contacts are adapted to be selectively coupled to a backplane of a chassis. The termination resistor is adapted to terminate signal lines when a jumper is coupled across select line card contacts.

Power control circuits that control the power sequencing and ramp rate of voltages applied to integrated circuits are disclosed. In one embodiment, a power control circuit comprises a delay resistor, a delay capacitor and an input transistor. The delay resistor is adapted to be coupled to an input power supply. The delay capacitor is coupled in series with the delay resistor. The input transistor has an emitter that is adapted to be coupled to the input power supply through the delay resister. The input transistor conducts current when a voltage across the delay capacitor rises above a selected voltage threshold of the input transistor. A power source is applied to a load in response to the conduction of the input transistor which is delayed by the time it takes to charge the delay capacitor to the selected voltage threshold.
