Full remote server backup over cstream using tar (excluding unnecessary files) (reports every 10 seconds)

The files are automatically uncompressed when they reach the destination machine. This is a fast way to backup your server to your local computer while it's running (shutting down services is recommended). A file named "exclude.txt" is needed at /tmp/ containing the following : /dev/* /media/* /mnt/* /proc/* /sys/* /tmp/* /home/*/.local/share/Trash /home/*/.gvfs /home/*/.cache /home/*/.thumbnails /etc/fstab /lib/modules/*/volatile/.mounted /var/run/* /var/lock/* /var/tmp/* /var/cache/apt/archives/* /lost+found/* Show Sample Output

Generate a directory path based on the date and time

Great for backup / restore scripts. May want to remove the %M/%S to group backups by hour. If using a script, set a variable earlier with the date command, then reference that variable. Otherwise, time will keep on rolling ;-) declare -rx script_start_time="$(date '+./%Y/%m/%d/%H/%M/%S')" mkdir -p "$script_start_time" Show Sample Output

Split a file into equal size chunks and archive to (e)mail account.

This is just a little snippit to split a large file into smaller chunks (4mb in this example) and then send the chunks off to (e)mail for archival using mutt. I usually encrypt the file before splitting it using openssl: openssl des3 -salt -k <password> -in file.tgz -out file.tgz.des3 To restore, simply save attachments and rejoin them using: cat file.tgz.* > output_name.tgz and if encrypted, decrypt using: openssl des3 -d -salt -k <password> -in file.tgz.des3 -out file.tgz edit: (changed "g" to "e" for political correctness)
