comment Is btrfs suitable as backup filesystem?
@JDługosz While it is possible to run a VM for ZFS, it is not desirable due to the resource overhead (RAM). It is indeed for backup purposes and therefore it is a separate, external disk. A NAS would not help if the house burtnt down, so this external approach allows for offsite backups too. By the way, btrfs also has support for various RAID modes. Please do not try to sell me on ZFS, I have a friend who tries to do that ;)

@JDługosz That does not help if the disk is directly attached to a Linux machine.

You still haven't provided one of the important details: the kernel version and distribution.

comment Can a suspended process be copied?
@user1750289 Have a look at Checkpoint/Restore in Userspace (CRIU). This is a heavy-weight approach though, so I suggest to write the results of the first pass to file and separate the interactive analysis tool in a separate program. Also, could you my question How do I list files in a directory? /s

@StephenKitt Solaar and ltunify use the same commands to trigger a pairing, it is unlikely that it would help with this problem.

comment How do I remove a user from a group?
This "works", but only because you have a single secondary group. usermod -G newgroup11 abc2 will put you in the secondary group newgroup11. Since the primary group is abc2, you will end up in both groups. usermod -g abc2 abc2 results in newgroup11 being removed from the secondary groups because it is not mentioned anymore. So for three or more different groups, this method won't work. See the other answers involving gpasswd for a better command.

comment grep invading my ps
[my]process. would match mprocessX and yprocessY (since [my] is a character class which matches on of the letters m or y, and . matches anything).

comment Is btrfs suitable as backup filesystem?
@wurtel The problem with --checksum is that you cannot really detect bitrot. The number of metadata changes (mtime, permissions, ...) and actual data changes will by far exceed that single file so manual inspection is not an option. So data checksumming (as provided by btrfs) is really necessary here.
