I set up my own mail server following the guide here: https://www.c0ffee.net/blog/mail-server-guide/ https://www.c0ffee.net/blog/mail-server-guide/ I also referred to https://www.gmass.co/blog/smtp-server-linux/ https://www.gmass.co/blog/smtp-server-linux/ I also looked at OwnCloud, but ended up just syncing from my phone to local Mac and doing backups off that regularly. You could also rsync to other devices. A raspberry Pi with a SSD at home would work fine. If you have a VPN set up on your own network (eg. an ASUS router), you could use it to host photos/backups/music. If you home IP address is dynamic, use a free DDNS provider so you can always connect to your home site. Just make sure you get a copy of those photos sooner than later!!
