vdirsyncer VS ImapSync

Have a look at vdirsyncer. Sync calendars to a local directory and then use eMacs to read them.

I found vdirsyncer which seems like a nice and promising idea similar to maildir which I already use with notmuch, even though it seems too opinionated and the support for Google calender seems largely untested/unsupported.

For getting ics files, have you seen vdirsyncer ?

On another topic, I maintain a tool to synchronise calendars (e.g.: events and todos) using CalDav (a standard HTTP-based protocol which a lot of calendar servers implement). I'm actually rewriting this in Rust full-time these days.

I used https://github.com/pimutils/vdirsyncer and made a cronjob for it on my host. The configuration is pretty simple - but always do a backup before testing! :)

Whatever CalDAV type calendar you go with (NextCloud and Radicale have been suggested here, Sabre/DAV, DAViCal and Baikal are other options), in case you need to sync calendars to it, you might want to look at vdirsyncer. This way, everyone can keep using his favorite app and you can still gather everything in once central place and have it all synced. Or you get everyone to set up DAVx5.

I have recently started organizing my calendars using `vdirsyncer` [vdirsyncer](https://github.com/pimutils/vdirsyncer)

Hm. Generally for folks who are familiar with the command line I suggest using vdirsyncer, a nifty little python program that lets you keep remote calendars in sync.

You see this https://imapsync.lamiral.info/ ? It's only for mails but it's a great solution.

I've had to do large email migrations before and honestly, imapsync is the way to go - https://github.com/imapsync/imapsync

Do your parents have a domain, or are they just using the provider's domain? I've set up my 1522+ to backup our mail accounts using MailPlus on the Synology, and IMAPSYC running on my lab server. But it's backup only, not archiving. That technology could be used to get to your desired state, but there's some work involved to make a secure connection from the internet to your Synology possible, sync/archive the mail, configure you parent's devices to find your device, etc.

Check out imapsync (https://imapsync.lamiral.info/) - I am using it since years and migrated tousands of mailboxes without any problems.

Check https://github.com/imapsync/imapsync

I would use https://imapsync.lamiral.info/ for email and sure there is another tool for contacts and calenders.

There are two solutions for this 1. Using a tool called imap-sync to sync all your emails (it has a great incremental sync). You can run it periodically via cron 2. Using the same or similar tool and export to a database.

If you want to sync from one IMAP server directly to another, there's also the very popular imapsync: https://github.com/imapsync/imapsync

Have a look at imapsync. Source: former web hosting sysadmin. Used this many times to move email.
