This will backup the _contents_ of /media/SOURCE to /media/TARGET where TARGET is formatted with ntfs. The --modify-window lets rsync ignore the less accurate timestamps of NTFS.

This will compress the root directory to an external hard drive and split it to parts once it reaches the 4 Gigs file system limit.

You can simply restore it with:

restore ivf /media/My\ Passport/Fedora10bckup/root_dump_fedora
cd <YOUR_DIRECTORY>; for i in `ls ./`; do tar czvf "$i".tar.gz "$i" ; done

Very simple and useful, you need to change the word "directory" for your directory

tar -zcvpf backup_`date +"%Y%m%d_%H%M%S"`.tar.gz `find <target> -atime +5` 2> /dev/null | xargs rm -fr ;

create an archive of files with access time older than 5 days, and remove original files.

Functions: rsync umount

connect to a remote server using ftp protocol over FUSE file system, then rsync the remote folder to a local one and then unmount the remote ftp server (FUSE FS)

it can be divided to 3 different commands and you should have curlftpfs and rsync installed

wget --http-user=YourUsername --http-password=YourPassword http://YourWebsiteUrl:2082/getbackup/backup-YourWebsiteUrl-`date +"%-m-%d-%Y"`.tar.gz

User: nadavkav
Functions: wget

this will connect to your hosted website service through the cPanel interface and use its backup tool to backup and download the entire website, locally.

(do not forget to replace : YourUsername , YourPassword and YourWebsiteUrl for it to work )

INFILE=/path/to/your/backup.img; MOUNTPT=/mnt/foo; PARTITION=1; mount "$INFILE" "$MOUNTPT" -o loop,offset=$[ `/sbin/sfdisk -d "$INFILE" | grep "start=" | head -n $PARTITION | tail -n1 | sed 's/.*start=[ ]*//' | sed 's/,.*//'` * 512 ]

Suppose you made a backup of your hard disk with dd:

dd if=/dev/sda of=/mnt/disk/backup.img

This command enables you to mount a partition from inside this image, so you can access your files directly.

Substitute PARTITION=1 with the number of the partition you want to mount (returned from sfdisk -d yourfile.img).

sudo dd if=/dev/sda of=/media/disk/backup/sda.backup

Functions: dd sudo
Tags: backup dd

This will create an exact duplicate image of your hard drive that you can then restore by simply reversing the "if" & "of" locations.

sudo dd if=/media/disk/backup/sda.backup of=/dev/sda

Alternatively, you can use an SSH connection to do your backups:

dd if=/dev/sda | ssh user@ssh.server.com dd of=~/backup/sda.backup
