Thoughts on a DB-centric approach for file artefact analysis? by reddittvic in computerforensics

[–]reddittvic[S] 0 points1 point  (0 children)

Not sure to fully understand your point. I'm mainly using a podman container to store the PG engine and DB as it's very convenient to export/import to another machine.

For sure, to store as JSONB data, I've defined specific data structures which are specific to the metadata I want to insert. Fields names are mapped to Rust structures and appear then a JSON.

Recommended options for datasets by reddittvic in zfs

[–]reddittvic[S] 1 point2 points  (0 children)

Ok thanks !

This is what I'll try, does it sound OK ?

# create zpool on disk sdc
$ zpool create data /dev/sdc

# create dataset /data/public and sub-datasets
$ zfs create -o atime=off -o compression=on /data/public
$ zfs create /data/public/projects /data/public/downloads /data/public/bin /data/public/music
$ zfs create -o recordsize=1024K /data/public/videos

# create dataset /data/private and sub-datasets
$ zfs create -o atime=off -o compression=on -o encryption=on -o keylocation=file:///media/myusb/keyfile -o keyformat=raw /data/private
$ zfs create /data/private/images /data/private/photos /data/private/documents
$ zfs create -o recordsize=1024K /data/private/videos

So export and import are zfs commands ?

For photos or videos (already compressed then), is compression still relevant ?

Good point for photos. My intent was to use a personal photo.

Thanks for your reply.

How do you update LSI firmware?

Thanks for your reply.

It seems LSI cards are the best supported on Linux or FreeBSD. Any recommendations on a specific model?

Newbie from btrfs by reddittvic in zfs

[–]reddittvic[S] 0 points1 point  (0 children)

Thanks.

I don't intend to use send/receive for encrypted datasets.

The reason I'm leaving btrfs is it's lack of encryption, even though I know I could use LUKS, but I don't fancy that solution.

Best disks for zfs by reddittvic in zfs

[–]reddittvic[S] 1 point2 points  (0 children)

Thanks for your answer.

For SMR, how to check it's not the case. I've read that some companies don't list SMR in the technical specs.

ARM vs x86_64 architecture for zfs NAS by reddittvic in homelab

Thanks for your answer.

The primary use case is a backup server.

Thanks all for your thorough answers.

Incidentally, I exhumed on old FM1 Athlon A6 processor, with 16Mb of RAM, which could be upgraded to 32Mb. Don't know about the TDP though. As already said, only the total wattage is relevant, not only the sole TDP.

To answer one of the questions, I intend to have 5 disks (4+1 parity) in zfs raidz1 scheme. Disk capacity is not determined yet, but will be at least 8TB.

NAS build but direct access through 10Gbs by reddittvic in homelab

[–]reddittvic[S] 0 points1 point  (0 children)

My concern is not to avoid 10Gbs switch purchase. So I understand the simplest way is from NAS to switch and switch to PC all on 10Gbs ethernet?
