Synology Snapshot vs Backup, What Should I Be Using?
I have a few questions on snapshot vs backup, any insights super appreciated:
(1) What is the philosophical difference between doing hourly backups and snapshots? I have zero intuition for this and was hoping others might chime in.
(2) If you use snapshots, how frequently do you set the snapshot to occur? What is Snapshot replication (it sounds like some kind of backup of snapshot data, like an alternative reality time machine)?
(3) It seems that snapshots maintain versions on disk, so reversion to earlier versions should be much faster than copying from a backup, but then if you use replication of the versioning, isn't that basically the same thing as the hourly backups? I'm confused; especially since cloudstation seems to automatically do some versioning stuff.
(4) Ultimately I’m wondering if I should (a) just stick with hourly backups on my Synology, (b) drop hourly backups and move to snapshots/replication, or (c) should I do both (belt and suspenders).
Would love to hear your thoughts on that (here or on geek gab). I also set up a poll to get a feel for what others are doing/using.
Thanks for any advice/pointers!
btrfs conversion was a total pain. One of the Synology reps told me the cleanest/easiest way to move it was via cloud station client on the Synology itself. Was a bit of a kludge, but did the trick. At least it was a one time thing.
Hi John, I'll explain what I have done on our Synology at work, which is different from my own Synology for personal use.
At work, I'm using the following backup strategies.
1. Backup my Sharepoints to a second volume on the same Synology (a DS1813+) via Hyperbackup. I was doing this every hour but switch to only once a day since I have migrated the versioning with Snapshots. See fallowing point.
2. Snapshots of my Sharepoints every 5 minutes from 7am to 6:55pm, keeping them 24 hourly, 12 daily, 7 weekly.
3. Shared folder Sync with another Synology at home which syncs the shared folder once a day.
We are not using CloudStation sync or Drive. Everybody work directly on a mounted shared point via AFP on their Macs.
So that way I have the versioning with the Snapshots, I also set them visible so that everybody has access to previous version without having to ask me or another admin for their files in case of mishap. I also have the Hyperbackup on a second volume so if by any bad luck the volume one gets corrupted I would still have the data locally on it. And, last but not least, I backup to an external destination so if fire strikes or theft, I still have everything elsewhere. I coule probably go without the Hyperbackup though but since it was already running before I migrated to btrfs I just reduced the number of backup to once a day to reduce the ressource it was taking while we are working.
For home, I use the Snapshots and backup my most of my folders using one way Cloud Sync one two 1TB Microsoft OneDrive accounts (part of a home office 365) and my Dropbox 1TB plan. The rest of my data is either redownloadable or temporary.
Anyway, hope that helps.
Huh... never thought about doing it with Cloud Station Client... that's an interesting workaround.
