Back Up Policy

 

PURPOSE, data save reliable.

 

Now, our file server have too many file, which include current use file and seldom use file.

Our file backup time is limited. But our file server size is increasing. It mean that we will not enough time to backup all file in the future.

 

And there are many bad thing  in this situation.

 

1. At last we have not enough time to do the backup.

2. When the backup time is too long, The backup time will more early. Just 18:15.  It will affect the lan speed. (OT Staff, Urgent Work)

3. When there are too many file in the harddisk, it will affect the harddisk maintenance.

4. When the harddisk breakdown, the recovery will be very long.

5. Search a usable data will need a long time.

6. We have all file in 1 backup file. This file is very very big (over 30g). When there is some 缺點 just as cross link, back sector. We cannot take it again. Very danger !!

 

 

 

Suggestion

 

1. Add the limited for each department.

2. Each department have two directory, 1 is current use , 1 is for burn CD by MIS Department.

3. MIS department will burn CD/DVD  Each month i(Each Department in Each CD ROM). After burn the CD ROM , the (burn cd directory files will delete) . Each time burn 2 DVD rom in a re-writeable DVD. 1 is master , 1 for retrieval. Burning file list would print out.

4. The first time do it is 28Feb2006 (Computer Department Burn CD). After this time MIS will burn it by each month. If the CD Rom is not full. burn it in re-writeable DVD ROM, with Full, burn it again in the no-rewrite cd-rom. The re-wirteable DVD ROM re-use it.

5. If the department file is over the limited. MIS department will delete the file from the earliest time.

6. After burn DVD, this DVD will keep in (Document Control Centre) and it can retrieval in the public computer which had CD Rom share. I suggest Document Control Centre because this department can control who lend and return this CD ROM.

7. And the other CD Rom keep In HongKong.
