Some things that can make the process better is to clear out the unused space, since the clone process using dd copies all sectors regardless of if they have currently used data. Once did a clean install of Fedora on an 80G disk, and did a disk image, and it created a 12G image file using lzop compression. Then cleared all the partition by writing nulls to the unused space, and the image size dropped to 2.5G. On my classroom machines have Fedora 22, and Windows 7 at the moment. Have an sda8 partition, where I store and ntfsclone image of the windows 160G partition that is about 30G in size of the about 55G of used space. Takes about 15 minutes to make a new complete image, and about 12 minutes to restore. Using a USB 2 flash the process takes about 8 minutes to restore, and 4 1/2 minutes from an USB 3. NTFSCLONE is a filelevel image process, so only backs up used space. Also, make separate partition images of the Fedora partitions on the sda8 partition, and can make full disk images to external drive of the disk. Also, have a filelevel program as part of project that I added at the request of a user called fsarchiver, and it can do file level backups, so it is similar to the ntfsclone for windows. Still recommend doing a full dd type clone, but perhaps using these images as quicker process. Actually, add the g4l option as part of the regular boot process, so the windows partition can be automatically restored by just selecting the option on the grub menu. Since once loaded it is running in ram, it doesn't require a cd or usb boot disk. What size disk/partitions are you imaging, and what times is it taking. G4L uses lzop for compression, which was about twice as fast as gzip when making images, but about 10% larger image size. Uncompression speeds where almose identical. > > Paul > -- > users mailing list > users@xxxxxxxxxxxxxxxxxxxxxxx > To unsubscribe or change subscription options: > https://admin.fedoraproject.org/mailman/listinfo/users > Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct > Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines > Have a question?
