Is there a way to create a partition on HDD as BTRFS (For Snapshots)? I Missed during setup / install. New to linux.. My LM 22.3 Cinnemon is installed on nvme and I Have a HDD of 4 TB, I want to allocate 500GB for snalshots and format it as BTRFS but I am not getting that option anywhere. Currently its formatted as ext4. New to linux.. this is just 1st week..

if the linux OS is on an ext4 partition, you can use BTRFS for the backup drive, but it will still only work with rsync method
chrome sky
oh, then no use of formatting it as btrfs? Dats wat ur saying?
sand aurora
it's your choice
do you want to erase whole 4 tb drive?
or just shrink a part of it?
chrome sky
No I mean if there are no positives / benefits of doing it, I would prefer not to mess with what is already up and running..
sand aurora
show result of sudo parted -l from big terminal please
chrome sky
Yeah shrink 500 GB of it, format as BTRFS and use for snapshots if that much is enough
chrome sky
show result of `sudo parted -l` from big terminal please

ok linux is on ext4
may as well not touch any of the hdd's
they're already all ext4
the only
chrome sky
Yeah all on ext4, but I wanted to go for BTRFS (If it can perform better) on SDB1 with 500 GB partition.. I dunno.. watched few videos on YOutube saying BTRFS is better for snapshots, so wanted to go for it.. but as ur suggesting that it wont bebenefetial, then no point in doing that..
sand aurora
it wont make a difference or "perform better"
chrome sky
just 1st week on Linux and already reinstalled it once and recently reverted with Timewshift 1 time..
chrome sky
it wont make a difference or "perform better"
Ok then, thanks for telling .. wont do it then..
sand aurora
the point is to direct timeshift to use one of those drives , say the sdb. which seems to be set to automatically mount to /mnt/Data
I will however refer you to a vid with a cool tip for your data drives.
chrome sky
yeah all are automounted.. i used disks option to do that.. earlier those were not mounting automatically.. now they r
chrome sky
I will however refer you to a vid with a cool tip for your data drives.
Yeah pls tell me.. but pls keep in mind.. m new.. doesnt know ABC abt linux
sand aurora
this guy in vid has tons of good info, and is relaxing to listen to
chrome sky
who? can u send me the link of any 1 of his video pls? wil sub then
sand aurora
i link from timestamp
chrome sky
Also if u can do me 1 more favor.. can u pls suggest me a book or something to understand Linux..
sand aurora
the part for the optimization
but u can watch all as well
before u do it, look at df -h command now (FSAVAIL)
and note the "filesystem available" column
chrome sky
Yeah, M already Sub to this channel.. Thanks 🙂

sdb1, sdc1, sdc2 you may want to optimize to 0 as he says
nvme0n1p2 you may want to optimize to 1
sda1 , also ext4. if it's data only u can optimize to 0
chrome sky
what does that even mean? Brother.. piity on me pls.. Linux is already complicated.. what ur telling must b valuable.. but I am not understanding what you are telling me.. Sorry is I am sounding SIlly
sand aurora
just listen to the vid for 10 minutes from timestamp
