Begriff UPS in Replication-Doku.

[Jochen Metzger]

Hallo,

in der Dokumentation zu MySQL wird unter replication:
genaue URL:
http://www.mysql.com/doc/R/e/Replication_Features.html

folgendes gesagt:

Shutting down the slave (cleanly) is also safe, as it keeps track of
where it left off. Unclean shutdowns might produce problems, especially
if disk cache was not synced before the system died. Your system fault
tolerance will be greatly increased if you have a good UPS.

Meine Frage: Was bedeutet UPS?

Gruß

Jochen
