Backup servicer
Draft definition. Technical and editorial approval pending.
A party appointed to take over specified servicing duties if an agreed trigger occurs. Data access, ongoing testing, transition deadlines and compensation depend on the engagement and facility documents. Labels such as cold or warm standby do not establish the actual obligations. Check whether the backup can use the files and perform the required tasks.
In practice
In a fictional arrangement, the backup receives a monthly file. A rehearsal finds that payment-history fields cannot be imported. Fix and retest the mapping before a transfer is needed, and document who maintains it. Receiving a file is not evidence that a servicing transfer will work.
