+# Backup my own way
+
+First thing first, I want to list my own devices, which I have through the years:
+
+- Laptop Samsung NP300E4Z-S06VN (Old laptop which I give to my mom)
+- Laptop Dell Inspiron 15 3567 (My mom bought for me when I go to college, I give it to my sister afterward)
+- Laptop Acer Nitro AN515-45 (Gaming laptop which I buy for gaming, of course)
+- Macbook Pro M1 2020 (My company laptop)
+- Phone LG G3 d851 (Kinda broken, the phone I used long time ago)
+- Phone Xiaomi Poco X3 NFC (Primary phone which I use daily)
+
+App/Service I use daily:
+
+- [Bitwarden](https://bitwarden.com/)
+- [Aegis Authenticator](https://getaegis.app/)
+- [Rclone](https://rclone.org/)
+- [Tailscale](https://tailscale.com/)
+- Google Keep
+- Google Drive (I use 200GB plan)
+- GitHub
+- GitLab
+
+The purpose is that I want my data is safe, secure and can be easily recoverd if I lost some devices;
+or in the worst situation, I lost all.
+Because you know, it is hard to guess what is waiting for us in the future.
+
+There are 2 sections which I want to share, first is **How to backup**, the second is **Recover strategy**.
+
+## How to backup
+
+Before I talk about backup, I want to talk about data.
+Specificially which data should I backup?
+
+I use Arch Linux and macOS, primarily work in terminal so I have too many dotfiles, for example `~/.config/nvim/init.config`.
+Each time I reinstall Arch Linux (I like it a lot), I need to reconfigure all the settings, and it is too much time consuming.
+
+So for the DE and UI settings, I keep it as default as possible, unless it's getting in my way, I leave the default setting there and forget about it.
+The others are dotfiles, which I write my own [dotfiles tool](https://github.com/haunt98/dotfiles) to backup and reconfigure easily and quickly.
+Also I know that, install Arch Linux is not easy, despite I install it too many times (like thounsand times since I was in highschool).
+Not because it is hard, but as life goes on, the [official install guide](https://wiki.archlinux.org/title/installation_guide) keeps getting update and cover too much case for my own use, so I write my own [guide](https://github.com/haunt98/til/blob/main/install-archlinux.md) to quickly capture what I need to do.
+I backup all my dotfiles inside my dotfiles tool in GitHub and GitLab as I trust them both.
+
+So that is my dotfiles, for my regular data, like Wallpapers or Books or Images, I use Google Drive (actually I pay for it).
+But the step: open the webpage, click the upload button and choose files seems boring and time consuming too me.
+So I use Rclone, it supports Google Drive, One Drive and many providers but I only use Google Drive for now.
+The commands are simple:
+
+```sh
+# Sync from local to remote
+rclone sync MyBooks remote:MyBooks -v --exclude .DS_Store
+
+# Sync from remote to local
+rclone sync remote:MyBooks MyBooks -v --exclude .DS_Store
+```
+
+Before you use Rclone to sync to Google Drive, you should read [Google Drive rclone configuration](https://rclone.org/drive/) first.
+
+The next data is my passwords, and my OTPs.
+These are the things which I scare to lose the most.
+First thing first, I enable 2-Step Verification for all of my important accounts, should use both OTP and phone method.
+
+I use Bitwarden for passwords (that a long story, coming from Google Password manager, to Firefox Lockwise and then settle down with Bitwarden) and Aegis for OTPs.
+The reason I choose Aegis not Authy (I use Authy for so long but Aegis is definitely better) because Aegis allows me to extract all the OTPs to a single file (can be encrypted), which I use to transfer or backup easily.
+
+As long as Bitwarden provides free passwords stored, I use all of it's apps, extensions so that I can easily sync passwords between laptops and phones.
+The thing I need to remember is the master password of Bitwarden in my head.
+
+With Aegis, I export the data, then sync it to Google Drive in my main phone, then sync it back to my backup phone.
+For safety, I also store Aegis data locally in all of my laptops (encrypted of course).
+The rule is you always need 2 phones for OTPs, one for carrying around, one always stays at home.
+
+The main problem here is the OTP, I can not store all of my OTPs in the cloud completely.
+Because if I want to access to my OTPs in the cloud, I shoud log in, and then input my OTP, this is a circle my friends.
+The easiest answer is the old phone, which is safely at home.
+
+## Recovery strategy
+
+There are many strategies which I process to react as if something strange is happening to my devices.
+
+If I lost my laptops, single laptop or all, do not panic as long as I have my phones.
+The OTPs are in there, the passwords is in Bitwarden cloud, other data is in Google Drive so nothing is lost here.
+
+If I lost my main phone, but not my laptop, I use the OTPs which is backup locally in my laptops.
+
+If I lost my main phone, and my laptops, I use the OTPs in my old phone.
+Then I go to nearest SIM store to recover my SIM, as I register my ID with it.
+
+The worst situation, I lost everything, my laptops, my phones (main phone and old).
+First step is recover my SIM, then log in to Google account using password and SMS OTP.
+After that, log in to Bitwarden account using master password and OTP from Gmail, which I open previously.
