Or you can automate it by scheduling a job in windows to do it every day (assuming you have an automation in HA that creates a snapshot every night)

net use x: /delete /yItâs funny⊠my automation has stopped working 2 nights ago and I have no idea why. It still creates the snapshot but doesnât upload it. I did just run the automation manually and it worked perfectly⊠Reall odd as itâs one automation that creates the snapshot, waits an hour and uploads it⊠and the automation is ON.
I have no idea why itâs just now screwed the pooch.
And today it works⊠I did change a few things around in dropbox as it was getting full but no reason that would have caused this⊠(the notifications werenât getting activated either for that automation. Maybe 0.87.1 fixed it?
Simply click on the snapshot you want to copy in the Hass.io Snapshots menu .In the bottom corner next to bin icon is a download icon . Download to your PC and keep it safe 
FWIW - I gave up and recently came back. I gave up because the pi was underpowered, SD cards died all the time, and HA updates constantly broke compatibility. So I switched to smartthings. In the end, it was too limiting. I got myself a used intel NUC, loaded hassio, and HA runs great. Now the updates can still break compatibility, but thatâs what backups are for!
Ah. I now have HA, so no more snapshotsâŠ
I moved to OnDroid XU4 with eMMC due to concerns with SD cards.
Have to say after a bit of faffing about with the install it runs really fast and stable.
Referencing @zegikniet - I do feel for you. Thereâs been times I had to slam my head against the wall. But thatâs the fun isnât it? Or not for you.
Heâs gone, last login was this post. HA is not for everyone⊠yet.
It never will be for everyone, it will always require some time and investment like with any kind of software. This person is probably better off with Homekit or Google Home.
This thread should probably be closed in my opinion as it is no use and it doesnât contain a question nor a solution to anything.
The SD card issue in my opinion is a big one. In order for any software or technical product to become mainstream it must have a low barrier of adoption and a high level of reliability. Many of us here work in software. I write automation tools for enterprises. I never once assumed my needs would be served by a PI to start with. But we must assume most users donât have this background. Hass.io is easy to get up and running and its almost so easy to use its pitfalls are of itâs own making. Automation is pretty addicting and soon a not so technical user has outgrown the PI + SD card combo but arenât aware and get frustrated. Iâm personally onboard with the bass install on a PI + SD being preconfigured to limit reads and writes. Let the use opt in to unlock advanced features with a big warning that the system could become unstable. This allows the novice to get their feet wet in relative safety and when they out grow it they can come to the great community here for guidance and a bigger build out.
Not had any issues for a long time with Pi3 B+, Genuine Pi power supply and Genuine SD cards- Sandisk or Samsung. Was new to this when I started and patience is virtue in this world, especially when things donât go to plan. Backups are a must of config files and every so often before upgrades an image file
Just 1 more voice to add⊠glad to see this thread used as a sounding board rather than a troll feeder. To that end, I have to give a +1 to adjusting hassio defaults for a more reliable experience. I am a newb to hassio, yaml and java, but have been a tinkerer for decades (already knew c, custom built/programmed drones, DIY 3dprinters, etc) so was able to get my pi3+ with sd working acceptably well for now (and likely at least a year with adjustments to recording and a 10A supply). I will probably get bored before than and invest in a nuc⊠but that doesnât help anyone who may be stepping into what they will feel is a trap for newbs.
That said, I think folks that have developed the required patience & research skills to be successful with (hope this doesnât sound too pejorative) âhacky projectsâ like the current hassio release are more of an exception to the average newb (also hope that didnât sound too grandiose). The reality is there are and will be many truly non-tech types (by 2020 standards) happening upon hassio as an intro to home auto⊠or even for an alarm system⊠and maybe even more folks just seeking to upgrade from limitations with popular hubs (wink, st, etc).
Hassio doesnât have to be a headache for these users. While it may be fun at times to observe some newb debauchery (a right of passage if you will), but there is limit to that. It is one thing when a newb is overly thankful for a simple config line that ended hours of frustration. It starts to become evil imho when newbs have to spend $ to replace broken hardware due to just a poor config for an assumed choice of hardware (getting started guide of course assumes rpi w/ sd⊠at the same time defaults to record all zwave entities including attributes, weather, etc⊠stuff even advanced users would rarely need).
Iâm all for defaults with no recording to help newbs, or at least just the bare minimum (binary states maybe). Then recording and its implications can be introduced as a âonce all is running smoothlyâ lesson⊠with appropriate bold warnings about instability, sd cards, etc⊠heck probably a good time to inject thoughts about a nuc. Something like a⊠âwe see you are running hassio off an sd and adding recordings⊠going down this road can reduce sd card life⊠after a point you need to consider a nuc or similarâ.
Kennethâs post above really brought the wisdom here⊠we are all human, and looking at it from a non-tech perspective we can easily understand the frustration. Sometimes it is hard to fully âwear the other personâs shoesâ, but in this case it should be easy enough for us to see why the frustration and how it could have been avoided. Wasting $ isnât fun for anyone, especially if the âhowto guide tells you to do soâ.
Java? O.o
âJava is to JavaScript what Ham is to hamburger, or what car is to carpetâ
Hehe, I am learning the basics of js and yaml now (so green I can still mix up java vs js)⊠one of the welcome side effects of this home auto project. I have had many friends tell me java is so easy⊠just needed a real reason to learn it and here it is. 
And youâre still mixing them up.
*js⊠lol I canât think and type at the same time.
Lol. Youâll figure it out one day.
Just wanted to revive this thread, as I presume the sentiment expressed by the originial poster resonates with MANY folks to this day. My relationship with the hardware was off to a rocky start. Fortunately,Iâm six months strong and my SD card is handling quite nicely (knocks on wood). While I deserve for this card to become one day corrupted (impromptu turning off power WITHOUT shutting down first out of frustrationâŠa BIG NO NO), I believe what saved my arse is regularly updating it with apt get updates/upgrades. Itâs still kickinâ.
I am highly considering getting one of those HDD USB drivesâŠbut theyâre super pricey. Iâd like to be prepared for when my SD card finally flips the bird at me.
EDIT: typo
You can get 1TB WD Passports for something like $50-60 USD, I wouldnât really call that pricey.
I suppose not if there wasnât a thing called a âbudget.â
