    Hello All, I have trouble recovering an Ubuntu 18.04 backup to a smaller disk on a different hardware. The original system is on a RAID (3TB) and the restore system is just a single drive 2(TB). The Backup is just 70GB. But recover complains that the last partition has to be shrunk more than 2%. How can I address that?

    Hi All, been testing ReaR for about a week now, I notice incremental backups doesn't work when BACKUP_URL=file:/// (in my case to an FSTAB mount), but when BACKUP_URL=CIFS:// works just fine, is this a known limitation?

    @chumunga
    In case someone else has the same question rear/rear#1146 I guess BACKUP_URL=file:/// is the same as USB

    Have a couple suggestions for the next REAR release: would like to see if the "lsblk" command could be added to the rear recovery; also can we get UDF, NFS, and USB_STORAGE modules loaded automatically? Currently I have to make sure I modprobe them before making a backup as well as having to add lsblk to /usr/bin in order to see if my USB device mountable, and in order to add the file, I have to mount a cdrom using modprobe udf. One last request is to see if ntfs-3g can be added as well, this would help to read a DVD that was created in Windows.

    An additional request; I would also like the ISO image to be created during a backup using OUTPUT=USB... (just incase I would need to create a bootable CD to do a recovery). Right now I can either have the ISO created as part of the backup, or have a bootable USB device, but not both.

    I would like to add /usr/bin/ntfs-3g to my mkrescue image... how do I add that to the local.conf file so I can ntfs-3g mount my external hard drive?

    @tomlauri_twitter
    Never mind all my questions above; I have figured it out on my own. I now can make a USB device, with ISO included in the backup, and can mount my "windows" external hard drive using ntfs-3g during rear recovery.

    Is there any options to backup external harddisk ( /media ) data using ReaR-rsync methodology ?

    Hello Folks, is there any recommandation how to handle an old debian lenny, which has to be migrated by p2v? I stuck, after creating a all- in-one iso, which can not be recovered into a virtualbox virtual machine. I read, that rear was made for this tasks (kind of), but it feels like it's getting mad at me when it comes to udev. what is your experience?

    Hello,
    I have created a backup of my system (disk 960GB).
    I need to restore on a 400GB and 480GB disk
    I have read that adding AUTORESIZE_PARTITIONS=true and creating a /etc/rear/disklayout.conf file would solve

    here is my disklayout.conf:

    lvmdev <volume_group> <device> [<uuid>] [<size(bytes)>]

    lvmdev /dev/rhel /dev/sda3 lea2mY-Uisa-TaBm-mCUR-Mr8Q-FV56-5eZL15

    lvmvol /dev/rhel home 53687091200b linear

    hello
    Anthony
    @Anth0nyME
    i can't find answer or sollution for my problem. please help me, if possible... i have a strange thing: powerfull hardware (2 x xeon silver), many RAM and 1Gb network link, but ReaR make backup too slowly. No more than 5000KiB/sec. "top" show me what gzip eat 98% of CPU but mpstat show absolutely different: ALL cores (20 in summ) stay at 96-99% idle state... How can i speedup backup process? Thank you for advice.
    Laurent G
    @xenlo
    I assume that the gzip is mono threat, so it take 100% of one core and the rest of your cores stay in idle
    Anthony
    @Anth0nyME
    I make backup to NFS share. If i simple transfer any data at this shared NFS folder, speed dramatically increased.
    @xenlo Thank you. Can you advice how can i change this situation...?
    It's possible to change gzip to another app to make process more faster..?
    Laurent G
    @xenlo
    few clues here:
    «an implementation of gzip that is multithreaded, pigz»
    «use GNU's xargs to launch as many processes as you have cores»

    @celikozl which distro and which version of it are you running? what version is syslinux (in debian it may comes with the extlinux package)?
    Is someone of you in Chemnitz at Cheminitzer Linux Tage 2020 #CLT2020?

    Hi, I am not entirely sure if this right place, but it seems that the repo gpg key at http://download.opensuse.org/repositories/Archiving:/Backup:/Rear/Debian_9.0 has been expired. (InRelease: The following signatures were invalid: EXPKEYSIG A39566C0A4AB7D54).
    Is this the right place or am i just wasting your time :) ?

    Hi guys. Really new to Rear and I'm just wondering if it's possible to recover to a drive that is smaller than the partition that was backed up? I found some forum posts from a few years ago suggesting it wouldn't work. Thanks.

    @uzyx-john

    Hello all, I just discovered rear and have a quick question. I have done a quick look through the docs and dont see what I am looking for obviously, but it may be there once I learn more.

    I would like to be able to save backups to a local hard drive that is not part of the operating system. Is that possible? yes or no works then I will do my homework.
