208:-based server. No client is necessary, as the server is itself a client for several protocols that are handled by other services native to the client OS. In 2007, BackupPC was mentioned as one of the three most well known open-source backup software, even though it is one of the tools that are "so amazing, but unfortunately, if no one ever talks about them, many folks never hear of them".

inherent in the differences between the protocols. Using tar or SMB transfers each file in its entirety, using little CPU but maximum bandwidth. The rsync method calculates checksums for each file on both the client and server machines in a way that enables a transfer of just the differences between the two files; this uses more CPU resources, but minimizes bandwidth.
279:
The choice between tar and rsync is dictated by the hardware and bandwidth available to the client. Clients backed up by rsync use considerably more CPU time than client machines using tar or SMB. Clients using SMB or tar use considerably more bandwidth than clients using rsync. These trade-offs are

BackupPC uses a combination of hard links and compression to reduce the total disk space used for files. At the first full backup, all files are transferred to the backend, optionally compressed, and then compared. Files that are identical are hard linked, which uses only one additional directory

Windows XP laptops with 10 GB of data each, and if 8 GB is repeated on each machine (Office and Windows binary files) would look like 100 GB is needed, but only 28 GB (10 × 2 GB + 8 GB) would be used. Compression of the data on the back-end will

solution, if the archive function of BackupPC is used to back up the disk pool to tape. BackupPC is not a block-level backup system like Ghost4Linux but performs file-based backup and restore. Thus it is not suitable for backup of disk images or raw disk partitions.
302:
When browsing the backups, incremental backups are automatically filled back to the previous full backup. So every backup appears to be a full and complete set of data.

It can back up Unix-like systems with native ssh and tar or rsync support, such as Linux, BSD, and OS X, as well as
Microsoft Windows shares with minimal configuration.

Version 4.x can still use V3.x repositories, but all new backups use a new format (seamless upgrade). The overall performance is higher than with the V3.x version.
