Re: OT: Linux EXT4 dump/restore equivalent?

It's unclear to me how a version of restore that supports ext4 would differ from a version of restore that supports UFS. AFAIK restore (unlike dump) is FS-agnostic: it must understand the format of the dumpfile, but it needs no knowledge of how the FS is represented on disk because it uses ordinary system calls (open, write, etc.) to access the FS. What you _do_ need on that recovery disk -- along with a generic restore -- are ext4-aware versions of the kernel, fsck, mkfs, mount, and (arguably) dump. I am very hesitant to use a backup scheme that doesn't have a clear recovery path. +1 ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Re: OT: Linux EXT4 dump/restore equivalent?
I haven't checked all the features, so I don't know if it includes restore for ext4. According to: http://www.sysresccd.org/Detailed-packages-list It does not contain any version of restore. There are a lot of Linux boot disks out there. I haven't found one yet that includes an ext4 compatible restore. Debian lets you roll your own, but you need to do that before a disaster. It doesn't include useful rescue CDs like FreeBSD does. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Add (preliminary) ext4 support - thanks to libext2fs which does all the job for us. Thanks to Gertjan van Wingerde gwingerde [at] gmail for the patch. Without even trying to start a flamewar, allow me to ask this question: Do they _really_ use file systems over there at Linux land without having an up-to-date dump/restore mechanism for that file systems? I can hardly believe that... Without wishing to bash Linux (I wouldnt be in my job without it,) its man pages are really not very up to date, as the manpage for dump fails to mention this. That's sadly normal. I found the attitude toward documentation in Linux being different from what you would call standard in the rest of UNIX world. Man pages are often out of date (if they ever exist), and pieces of documentation is scattered across the the web, in user pages, wikis, and discussion forums. The concept behind this seems to be: Nobody reads man pages, so we don't write them. I havent used slackware in many years but it used to be my distro of choice until I moved to FreeBSD. Was my first PC Linux, too. :-) On 28/06/2012 20:02, Chris Maness wrote: Is there an equivalent dump/restore ap for a Linux ext4 file system? I am running the latest Slackware, and I would like to make backups like I do for my FreeBSD box. Have you tried the original tools provided by the OS? Do they perform as intended? Maybe do some testing and see if they are sufficient for dealing with ext4. That would be my first impression: Use what's there and see if it works, as it _should_ work (given fundamental UNIX basics).

I am very hesitant to use a backup scheme that doesn't have a clear recovery path. Fair point. I've used the rescue mode on the centos boot CD before, but its not too hard to build a custom centos livecd. I made a pxe bootable version for use at work so we can ssh into it without needing an IP KVM, but I'll try and make a new ISO for you if you like.
