|
//
|
||
|
|
// * Past backup exports.
|
||
|
|
// * An import downloading and parsing the manifest of the last complete backup.

// Storing this data in the database provides continuity.

// * Backup exports can reuse fragments from previous Backup exports even if they

|
|
// don't complete (i.e. backup export resume).
|
||
|
|
// * Backup exports can reuse fragments from the backup import, if any.
