[petsc-users] storing many petsc objects in a single file

Hey there,

For simulations, its useful to store the history as a series of state
vectors.  For simulations with many time-steps it can get annoying to store
each state vector as a separate file.  It would be useful if there were
some way to manage a database of petsc vectors.  To save the current
time-step, append the state vector to the database. To restart a
simulation, load the corresponding state vector out of the database.

Is there a standard way to do this in PETSc?
