# 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.

This was initially not implemented simply because I forgot about the
size limit of constraint names in PostgreSQL (63 bytes). Using the old
technique we can't add foreign keys for certain tables. For example,
adding a foreign key on
protected_branch_merge_access_levels.protected_branch_id would lead to
the following key name:

    fk_protected_branch_merge_access_levels_protected_branches_protected_branch_id

This key is 78 bytes long, thus violating the PostgreSQL size
requirements.

The hashing strategy is copied from Rails' foreign_key_name() method,
which unfortunately is private and subject to change without notice.
