Command Time (min) GB/min -------------------------------------- `cp -r` 33:50 ~1.21 `rsync -r` 32:15 ~1.27 `backr (0.2.2) 22:58 ~1.78 `backr -apt 3` 20:26 ~2 `backr -apt 7` 16:36 ~2.49 This test was conducted by using the `time` command to measure the run time of each program as it copied 41GB of data from a remote location to a remote destination. Take the results with a grain of salt as the test is very simple and was performed in a very loosely controlled environment. Specs of test Machine: Cpu: i7-4770 @ 3.9GHz OS: Fedora 28 4.16.14-300.fc28.x86_64 Rust ver: rustc 1.26.2 (594fb253c 2018-06-01)
Backup all data in the Home directory $ backr -a -s $HOME -d backup_dir Update an existing backup, showing a progress bar and using 5 threads $ backr -aupt 5 -s $HOME -d backup_dir Passing a custom regex so that only files/folders that match will be copied $ backr -r ".*(\.bak|\.cpp|\.rs)" -s $HOME -d backup_dir
-a, --backup-all Backup all files found, overriding the regex. Because of this, it conflicts with the regex option. -h, --help Prints help information -p, --progress Displays a progress bar during the backup. -V, --version Prints version information
-d, --destination <DESTINATION_PATH> The path to the location you want the data saved to. -o, --output_file <output_file> Specifies the location that failed transfer paths are written to [default: "<DESTINATION_PATH>/backr_log.txt"] -r, --regex <regex> Passes a regex to the program to only backup matching files and directories. [default: "Documents|Downloads|Movies|Music|Pictures|Videos"] -s, --source <SOURCE_PATH> The path to the User directory you want to backup. [default: <CURRENT_WORKING_DIRECTORY>] -t, --threads <NUM> Number of threads that will be used to backup files [default: 2] -u, --update <update> If this flag is set, backr will check the metadata of the source file and the already existing destination file, and will keep the newest one. [default: false]
