Yeah, that is what I am thinking. I am using duplicity for backups, so I can probably back up to a hard-drive, take that to work, sync it to my backup provider, then just do incremental backups from then on.
However, I think duplicity really wants to do full backups every X months, so I'm not sure the best way to handle that.
I don't know whether it's important to do a full backup for performance, but you'd need to do that if you wanted to remove old backups. It looks like the term for a full backup that reuses already pushed-over data is a "synthetic full" backup, and duplicity can't do those -- when it does a full, it pushes all the data over again.
I have never used it, but Borg Backup does appear to support this, if you wanted an alternate that can do this.
EDIT: However, Borg requires code that runs on the remote end, which may not be acceptable for some; you can't just aim it at a fileserver. duplicity can do this.
I have also never used it, but duplicati looks to my quick glance to be able to work without code running on the remote end and also to do synthetic full backups.
Another alternative is to setup a backup server at a willing friend/family members house so that you can physically take the drive and just upload any new changes later.
Or, pick up 2 backup drives, keep one at a friend/relative's house, then just swap them every time you visit.
I keep a drive at my parent's house in case of emergencies. Backup frequency is essentially every few months, but I also have the local portable drive with real-time sync I can snag on my way out.
