Help: `Set the number of days deleted files should be kept when creating a bucket.
On bucket creation, this parameter is used to create a lifecycle rule
for the entire bucket.
If lifecycle is 0 (the default) it does not create a lifecycle rule so
the default B2 behaviour applies. This is to create versions of files
on delete and overwrite and to keep them indefinitely.
If lifecycle is >0 then it creates a single rule setting the number of
days before a file that is deleted or overwritten is deleted
permanently. This is known as daysFromHidingToDeleting in the b2 docs.
The minimum value for this parameter is 1 day.
You can also enable hard_delete in the config also which will mean
deletions won't cause versions but overwrites will still cause
versions to be made.
See: [rclone backend lifecycle](#lifecycle) for setting lifecycles after bucket creation.
