In the mids of all of those "pretend" youtubers that pretend to know something, it's good to know there's at least one channel with true quality content. Even if I already know what you're saying, it's still ever so fascinating to watch your videos, never know when I might something new. So in short: A very big thanks for your awesome videos

Great presentation. For clarification, when you have to "go to IT to restore a backup of a file", if that file is anything older than a week or two, they are typically going to an offsite backup - usually a data tape - and restoring from that. So when they sigh and say that the restore will take 12 hours or 1 day, its not laziness or disorganization. They literally have to determine which tape they need from the backup set, call or email the tape warehouse company and arrange return of the tape, wait for delivery, insert tape, sometimes perform a read command which indexes the tape data before they can check what they can restore from it, then restore the data to a temp folder which can take an hour or so depending on where the data is on the tape physically, then put it somewhere the user can access. All the while they also have to update the ticket and manage update queries from the user who may be anxious for their file(s). Also, this is not unusual at all - almost all medium to large businesses have offsite backups on a specific retention period, and many of them still use tape as it is very high capacity and quite quick to backup a lot of data (LTO tapes are up to 18TB each currently). TL;DR: don't get too frustrated at the IT team when they're restoring a lost file and it takes longer than you expect, it is often a laborious process for them, and often not possible for them to speed up significantly as much of the time is waiting for the delivery or waiting for the restore process.

Regrading snapshots: I would have loved to hear a word about "recycle bin" on a Synology vs. Snapshots ... Shall I get rid of the bins? Or are they useful as an hourly snapshot might miss a new file on the NAS that got deleted before a snapshot is taken? And will the bin also get snapshooted?

Just got my 920+ and am finding your channel very helpful as a microbusiness owner and someone who plans on using the NAS for multiple tasks. Your overview of snapshots makes lots of sense, as I was trying to figure out the backup options (full, incremental, etc.) and realize now that snapshots play an important role there as well. So, if I have setup retention policy in ActiveBackup do I also need to turn on snapshots in Snapshot Replication for ActiveBackup, or does ActiveBackup already use them automatically? (given that I don't see an option for incremental backup).

Generally i use snapshots locally + snapshots replication to offsite in case on remote system i like to see it as it is on original NAS. I combine it with HyperBackup in cases, when i want to have backed up data more secured (encrypted, compressed and via password encapsulated) on remote backup NAS. Both have advantages / disadvantages. In some situations, snapshot versions take more disc space of backup, then hyperbackup versions.

@SpaceRexWill 2 жыл бұрын

For me I only use snapshot replication when I want someone to be able to recover instantly, like if the onsite NAS crashed they would drive offsite, pickup the backup and bring it to the office. For any other case I use hyperbackup as it gives you compression, clear versioning, and just overall ability to recover a bit better in case of a full blown disaster

After owning a DS1817+ since new for file storage but for what I am now calling my Homelab - thanks to learning the name from all the KZfaqrs - I am finally setting up snapshots. But one thing that is confusing me; replication vs. snapshots. I did not realize I could set up a snapshot schedule in the snapshots section and so set up snapshots in the replication section. That duplicated all my shares with a "-1" suffix, but also created snapshots for both shares and their duplicates, or so it would appear. Now I don't know what I should do regarding how to configure them. Have you created a video about the differences? If not, I think that could be a great topic for you to cover.

@davidmiko8954 Ай бұрын

Hi SpaceRex, thanks for this overview. very useful! I am wondering if this is effectively the same thing as versioning in Drive Share Sync? And does it duplicate the data if you have both running? We have two separate offices which are synced over Drive ShareSync. Both units are identical and both sides worked on by separate teams simultaneously. It works mostly well but we noticed one of the units has a lot more of the data used up (by several terrabytes). We were reducing the number of versions in Drive share sync to try to reduce the data hogging but I am now wondering if the space is not actually released that way?

The snapshots of those folders are completely independent, correct? I can put a file in a shared folder, it will get synced to the other shared folder. If both are doing snapshots, that file will then be in each folder's independent snapshots. I can then delete the file from one of them, Synology Drive will delete it from the other, but it will be in the snapshots on both sides?

@michaelrobinson9643 Жыл бұрын

Where long term snapshot can help may be if you are absent for extended periods and you want to have a snapshot present that won't be overwritten in absence. This would be useful for example if you were hit with crypto while away... and your NAS diligently replaced all snapshots with ones representing your encrypted data. Osentisbly your backup would cover this... but it is a scenario where a longer hold may be good. Rate of data change would be a factor in this. I use a long hold for things like my media - pictures, music etc where I'm not deleting just occasionally adding.

So this system does not really care about files. All it cares about is the underlying data. In your case where you edited 1KB of meta data, of a 50 MB file, all BTRFS sees is a change to the 1KB of data. Meaning that the previous version of that file is simply different by 1 KB, so the snapshot “costs” 1 KB As for a recycling bin I would leave it on, but empty it every night. It’s nice to be able to grab the file as it was just before it was deleted

BTW, I do have full external backups of all this data and update that backup after every five or ten newly added rips, which could translate to a new backup every couple of months or so.

You absolutely should snapshot! The beauty of snapshots is if nothing changes, they take up no space. They will just be a safeguard in case a computer gets a virus

@@SpaceRexWill I hear you, but should my NAS become encrypted via ransom ware or all the files corrupted from a virous, then the snapshot will fill my volume and not be able to snapshot everything changed as I have currently less space left than is used, so I'd have to resort to a wipe and restore, or am I missing something?

@SpaceRexWill Жыл бұрын

In that case the virus will get an error when your volume is full. After that you can just restore the shared folder to a clean snapshot, and boom, in 2 seconds you have your volume back up and running

So if you disable 'record file access time' then the timestamps on files never change? Or is this something else? I like to see files sorted from newest to oldest at times.

@SpaceRexWill Жыл бұрын

This is only for logging when a file is opened, not when it’s modified. Turning off access times will still let you sort by date modified

If users only have access to their own home folder, can they not access #snapshot? If the users are granted access to the shared homes folder there #snapshot is, then couldn’t they also at least view other users’ home directories, which seems problematic?

I just started using snapshot replication on your advice. I'm seeing red minus signs on some of the folders I have snapshots enabled on. I can't figure out what the minus signs on the snapshot icon means? Any ideas?

That just means they are read only!

@SpaceRex oh, interesting. It seems to be on some, but not all of the snapshot files in various folders I set up for snapshots but I thought I set them all the same

That's the easy case. Taking snapshots of /Homes is weird. Users won't have access to /Homes/#snapshot so they can't self-admin the files they will most often need to recover. Docs say that (on WIndows) the Previous Version tab on file properties can be used, but I've never seen anything appear there on any machine on the network. If there's a solution where users can self-admin their Home folder, please let me know.

@SpaceRexWill 2 жыл бұрын

Yeah, because of the way home folders work (using sambas remapping) it is a bit odd. Best case might be to use drive versions? Then users could self administer

hey, but a ransomware can encrypt even the snapshots folder, isn't it so ? what do you do then ?

Would there be a reason that a particular folder would not be made available in the snapshot setup list? My main "Home" folder isn't there. There is a "Homes" folder but not my main home one that is where the majority of my stored content resides.

the home folder is within Homes so if you snapshot homes you can recover your home folder

I messed up my Plex library by activating Snapshot on the Movies folder (no replication), because Plex scanned the snapshot folder. Now, the Plex library shows broken associations, duplicate movies with missing files everywhere. I haven't been able to recover the original Plex library, because its snapshot was made after the Movies folder had been processed by snapshot. How I solved the problem: - I made snapshots invisible in the movie folders which are scanned by Plex. - I rescanned all folders with Plex, optimized the database and cleaned the bundles, stopped & restarted Plex and everything seems to be back to normal.

Would making the snapshot folder visible make your snapshots vulnerable to hackers (since they can see that you're using snapshots)?

When you are talking about recovering from a ransomware attack, are you assuming that the Synology was NOT encrypted ? I'm a bit confused because, if it was the Synology that was ransomwared / encrypted, I would assume that the Snapshot files were encrypted and therefore of no value.

@SpaceRexWill Жыл бұрын

That’s the beauty of this. If they encrypt the files over SMB or any non admin account they cannot encrypt the snapshots as they are read only

Thanks, as always for the FANTASTIC video[s]. And here is a quick and dumb question. I THINK I know the answer, but want. to triple check. Are there any RULES about deleting individual snapshots? Are there any DEPENDECIES? Meaning, can you ARBITRARILY delete any random snapshots you like? I can't think of a reason you would need to... But let's say you have 200 snapshots and you want to RANDOMLY delete 70 of them.. Contigious ones, discontinuous ones etc [10 recent snapshots, 30 very old ones, a few in the middle etc.. Is that allowed? Or certain snapshots NOT allowed to be deleted. Thanks for your words of wisdom. - Eric ZORK Alan & Sweetie [ Professional Poets & Bed 🛏 & Beer🍺 Vloggers ]
