CompTIA Server+ SK0-005 CompTIA Study Notes

A differential backup is a backup method that protects all the changes that have occurred since the last full backup. A differential backup copies all the files that have been added or modified since the last full backup, regardless of whether they have been backed up before or not. A differential backup does not reset the archive bit of the files, which means they will be backed up again in the next differential backup. A differential backup requires more storage space and time than an incremental backup, but it simplifies the restoration process, as only the last full backup and the last differential backup are needed to restore the data

Open-source software is software that is freely available and can be modified and distributed by anyone. It usually requires very little technical support and has no licensing fees. Therefore, it would be the lowest cost solution for an application that does not need much support.

Robocopy (Robust File Copy) is a command-line tool that can copy files and folders between Windows servers or computers. It has many features and options that can ensure all the data is copied consistently, such as retrying failed copies, resuming interrupted copies, copying permissions and attributes, mirroring source and destination directories, and logging the copy progress and results.

GPT (GUID Partition Table) is a partitioning scheme that allows creating partitions on large hard drives (more than 2 TB). It supports up to 128 partitions per drive and uses 64-bit addresses to locate them. MBR (Master Boot Record) is an older partitioning scheme that has limitations on the size and number of partitions (up to 4 primary partitions or 3 primary and 1 extended partition per drive). To provision a new 4 TB drive, the technician should partition it using GPT. Verified References: [GPT], [MBR]
