# This is the 1st commit message:

Add `copy` backup strategy to combat file changed errors

The backup Rake task used to stream data directly from the live
data directory into the backup. Under many circumstances this worked
OK. However, really active instances would experience a 'file changed
as we read it' error - especially with data like the registry. This
now copies the data first, then compresses it. It will take a bit
more disk space while the backup is in progress, but it's a
necessary thing.

- Location in which to add `gitlab_rails` configurations
- Reminder to run `gitlab-ctl reconfigure` after changing gitlab_rails

Sometimes admins will change the LDAP configuration, not realizing
that problems will occur if the user's LDAP identities are not
also updated to use the new provider name. This task will give
admins a single command to run to update identities and will
prevent having to run multiple Rails console queries.
