I've been using CrashPlan to back up my home Linux server for years. Lately it seems to be behaving oddly: I recently added about 20GB of files and it suddenly said it had 950 GB of files to back up but never seemed to finish backing them up. I just happened to look today and it finally says it's done with the backup job. I'm wondering what other options are out there that people recommend.

• Backblaze would be nice but doesn't support Linux with its apps; instead I'd have to use Restic or some other tool. Not the end of the world but I'd like a nice GUI tool.
• iDrive.com looks promising and the price is right, but I've never heard of them and don't know how reliable/secure they are.
• rsync.net and borg seem like a nerdy solution but kinda expensive.

What are some other ideas that won't break the bank? Or thoughts on the above providers? Thanks
