Telegram says that one can send files up to 1.5 GB. Does that mean in total or per file? If it meant per file, one could just misuse that as a backup service, right? One could pack up data in packets of like 1 GB, encrypt them and upload that to a chat with oneself.

Is there some official quota or would one just get a message eventually for abusing the service?

I have asked the Telegram support a few times about this, since I do indeed use it as a backup storage. Their answer was that there is no limit and they even advertise with it:

Store your media in the cloud.

Telegram has no limits on the size of your media and chats.

I have uploaded 2-3 Terabyte of data on Telegram and there was no limit so far.

  • So how do you do it? Manually putting files there or something more automated? – Martin Ueding Oct 17 '18 at 17:13
  • What a coincidence that you ask that. I stumbled upon this question when checking if someone had asked the question I had already: https://superuser.com/questions/1367443/how-to-programmatically-upload-files-to-telegram And there I also link back here. – Fabian Röling Oct 17 '18 at 19:19
  • Do you think there is a file upload speed limit on Telegram? I have 200Mbps fibre connection which usually gives 35 MBPS upload speed. But with Telegram, it can max reach 3-4MBPS. – shashwat Jul 26 '20 at 14:17
  • Yes, I think there is one, as well as for downloads. It's a lot slower than my internet speed as well and seems to depend on the day or other factors. – Fabian Röling Jul 26 '20 at 16:46

Indeed, it's meant 1.5GB PER FILE.
I guess there is either some kind of account storage limit or some limitations occurring when abusing.
But, still, no official documentation is available about this.

You can do encrypted backups on Telegram clouds with PGPgram. It uses gpg to encrypt your files and lets you upload files of any size. From version 0.2 it even lets you backup YouTube videos and channels.
