I've been the maintainer of G4L project on sourceforge since 2004. I build in on my Fedora 35 system at moment for next version. Last release version was built on Fedora 34. It is a bare metal backup system by default, making disk or partition backups that can be restored. Basically a dd image compressed using lzop or gzip. Can back to local disk or via network (default is ftp using ncftp). Does have fsarchiver include, but only tested it once. Had a user request adding it, so didn't and did hear it worked will for him. But being a bare metal backup, it copies everything. Clearing unused sectors before greatly reduces size of image. Using lzop is faster than using gzip, and image only slightly larger. Do a image every few months, but use rsync to copy critical directories between machine for things that need more often backups.. Recently migrated 3 machines from regular hard disk to ssd disk using clone option. With 1T drives it took 4 to 7 hours, so speed is dependent on unbuffers speed. Made the mistake of hooking an ssd disk via a usb 2 adapter on the one that took 7 hours, but notebook only had 1 disk bay.. Kernels are built from source kernel.org, and try to include most disk and network controller. Boots from CD, or from USB, and can be added to a regular grub2 menu with 40_custom addition. Has a UEFI boot option, but haven't figured how to do a UEFI boot from grub2 setup. Is text based using dialog screen. Before retiring used it at college a lot. Could restore Windows 10 partition in about 10 minutes. Whole disk took about 45 minutes with Windows 10 and Fedora. Also, used udpcast to image one system in lab to other 19 machines using the multi-cast in about 45 minutes. There is also G4U, Clonezilla and other similar programs. > Bill > > _______________________________________________ > users mailing list -- users@lists.fedoraproject.org > To unsubscribe send an email to users-le...@lists.fedoraproject.org > Fedora Code of Conduct: > https://docs.fedoraproject.org/en-US/project/code-of-conduct/ > List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines > List Archives: > https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org > Do not reply to spam, report it: > https://pagure.io/fedora-infrastructure/new_issue +------------------------------------------------------------+ Michael D.
