By default, we allocate 20% of server space for backups. If existing backups on the server exceed the allotted space, Borg will not create new backups or do anything else which requires a backup (staging pushes, clones, etc).
Why would that happen? Maybe you have a really large site. Maybe you take 24 manual backups on the 30 minute mark because you're paranoid. Whatever the reason, 20% doesn't always cut it. Fortunately, you can increase this value.
Accessing the Config File
The available space varies per server size, but you can change it with this command:
Contents of the Config File
Once you're in that file, it will look like this:
version = 1
segments_per_dir = 1000
max_segment_size = 524288000
append_only = 0
storage_quota = 11000000000
additional_free_space = 0
id = (hidden for the KB, will show on your server)
key = (hidden for the KB, will show on your server)
The value you want to change is "storage_quota". Save, write, and exit the file.
It's in bytes and converts to GB like so:
1 GB = 10^9 bytes = 1,000,000,000 bytes
