回復 馬後砲 ##1 的帖子
我的真實方案:
Server[1] -----(2)-----> Remote NAS[3] -----(4)----> External HD[5]
[1] Disk imaging
(2) VPN Internet connection to remote site;
a) incremental backup individual files
b) Snapshot SQL data, then zip, send out
c) Do it automatically every night
[3] NAS located at remote site, online connect with internet, keep a daily copy of last night + weekly copy
a) User can retrieve last night copy from NAS, if required
b) Make a snapshot every week in the NAS;
(4) backup selective weekly snapshot to attacked USB external HD
[5] The USB HD keep forever monthly data:
a) i.e. the external keep the first week snapshot every month
b) the data in external HD will never be deleted
c) once it is full, buy a new HD and continues the same monthly backup
d) after monthly backup, the other 3 weekly snapshot will be deleted, i.e. keep the monthly backup on-line until too old |
