Snapshots vs Backups vs Replications

Have you been told, that snapshots will replace backups? This is like the biggest myth ever. Today we will be exploring and comparing the 3 different technologies (snapshot, backups and replications), what are the use cases and my recommendations

please please don't have background music. i just want to listen to you, not some music :) Otherwise thank you for the great video!

When you get into the content you shouldn't use background music. It's very distracting.

[fayannefoo]

Thank you Charles! This is a great video, I find myself coming back often to recap on these important concepts.

[sygad]

your content is incredibly useful and you present it very well, but please, PLEASE kill the background music, you are much more interesting than that audio assault

[raghav]

Can you please lower background music for future videos, it distracts from understanding the concept. Thanks.

[sayeda.]

Is there another version of the video without background music? If no, could you please provide us with a one🙏?

[vicmann]

Man, you've helped me a lot with this video.

[mydingoman]

Very informative, unfortunately it became unbearable to focus on what you were saying with your music in the background. I see now many people were having the same problem. Thank you however for your explanation.

[tweber]

I don't understand the background music. It is supposed to be an IT Tutorial not gym workout tutorial. I cannot focus on what he is saying.

Excellent video! I learned a lot. BTRFS was designed for massive enterprise installations. It is slow on home desktops. DJ Ware did an excellent comparison of file systems. F2FS shines on home desktops with SSDs and is what I use on all my systems. Snapshots can lull people into thinking of them as a real full backup. It is much better to create a full system image or functional clone, plus extra backups of irreplaceable files in Home, configs in etc, and the like.

On AWS RDS Postres, is it possible to have a db backup, not a dumb or snapshot, but a really full backup such as with pgbasebackup.

[hannulehto]

Please upload this again with NO music.

[SwatiRana-ld]

is not the synchronous replication better than the backup since it is replicating the data in live time rather than backup which is happening at a particular time in the day? Please clarify. Thanks

Hello everyone. I’m trying to understand how much space I need to allocate to my VSS volume assuming the operating system is stored on a 1 TB volume taking up around 200 GB. Next data is stored on another volume in the same raid 5 array taking up around 2 TB of data. On a 4TB volume. I appreciate the help.

Awesome explanations, but the music, maybe Vivaldi down low..

[mmroshani]

the best part was the suggestions. thank you for your work sir.

[dhananajaykrishna]

Either remove the bg music or keep it low... It has taken a toll on the explanation.

This is good. I have similar conversations reguarly about the difference between snapshots, replication and backup.
The only point I disagree with, which he only mentions bfriely, but backups are are NOT archives.
In one job, I had to restore 12 or so users Notes email boxes from about 5 years prior - several years worth of monthly full backups.
If I recall correctly, they'd all expired from the NetBackup catalog, and they'd changed from DLT to LTO tape in that time, so we didn't have the catalog information for where the data was, but they still kept the tapes.
So basically spent 6-9 months running pase-1 then phase-2 import on hundreds of DLT tapes on the 2 rusty old DLT drives they'd kept. And then restore the data to a dedicated PC and burn it to DVD to give to the lawyers (2 copies - defence and prosecution). About 20% of them failed, either at the import or restore point.
But the case went through. The prosecutors won. I have no idea if they used any of the evidence I'd restored via my very long restore process which ended up with about 100 DVDs being created.
Oh well, it kept me off the street for 9 months, even if it was boring as hell.
But things have changed a lot in that time. I'm talking about 15 years ago, restoring data that was already about 5 years old.

Personally, I've always considered snapshots to be a "System Restore" solution. Great for recovery in case of issues with updates (highly recommended when using rolling release distributions). But not a backup solutions. This is why my snapshots are configured to only create a new snapshot when I install, remove or upgrade software. It also makes sure there are no more than 10 snapshots available on my system, by removing the old ones daily at 7 P.M.

[jothain]

I've been thinking it's quite like this indeed. I've been using snapshops like before bigger system changes that could result in undesired concequences. But I still try to do like weekly backups.
