A processing module encodes data using a dispersed storage error coding function to produce a set of encoded data slices and identifies storage units for storage of the set of encoded data slices. The processing module determines that a storage unit of the storage units is unavailable, where the storage unit is targeted to store an encoded data slice of the set of encoded data slices. The processing module selects a foster storage unit of the storage units for temporarily storing the encoded data slice. When the storage unit is available, the processing module transfers the encoded data slice from the foster storage unit to the storage unit.
