Because when I try to migrate using the built-in backup, the compression process quickly fills up my disk. I still had around 60GB free space, but during backup the disk goes full and fails.
However, if I just manually compress the entire /var/discourse folder, the archive is only about 30GB (the folder itself is about 34GB).
Because the capacity is released directly when it is full, I took a screenshot at 80%.
So my questions are:
• Can I simply tar/pack the entire /var/discourse folder, move it to a new server, extract it, and then run Discourse?
• Or do I have to follow the recommended way (database backup + copy uploads separately)?
• Is there any method to avoid the disk filling up during the backup compression process?
