I have "176 APPENDABLE" entries in DEDUPLICATION STORAGE FOLDER,

and "64.0 KB of 50.0 GB " entries in DEDUPLICATION STORAGE FOLDER.

After talking to tech support......I gave up and wiped the disk clean and started from scratch with a

NEW and EMPTY de-dup folder, ran FULL backups over the weekend.

From what they said, de-dup doesn't append.

Every time a new job starts, it creates a new file and goes into overwrite mode.

At least tape jobs know how to append.

Now, there are: 

70 64KB of 50GB files;

164 (FULL) 50GB of 50GB, and;

21 (not full) "appendable?"

As per the design Dedup creates OST files each of 50GB. Initially there will be no OST files

in the dedup folder, once you fire a backup job 10 OST files will be created each of 50GB.

Depending on the media set selected for a backup job the OST files will be overwritable

and appendable. As per your post you have the below OST files

328 MEDIA FULL - these OST files are full(50GB) and they may be overwrite protected or overwritable

176 APPENDABLE - these OST files are appenable and will be use if the jobs are configured to append.

64.0 KB of 50.0 GB - scratch OST files which will be used for any overwritable jobs.

Note: 10 -20 blank OST files is a normal scenario, there should not be excess of these files else

you will run short of space on the dedup folder.

Solution 1: (SP1) failed, "This update could not be installed"

Solution 2: LiveUpdate 3.3 is 32-bit. Is there a 64-bit version?

Also, after updating SP1 successfully, will I have to do something

else, or will ALL the extra OST files go away(there are over 800)?

After installing the SP check the behavior of dedup. Also click on Tools->Options->Media

management-> select "use recycable media before using scratch media" so that the OST

files whose retention period has ended will be used for next overwrite operation.

Hi Thomas,

 

If you run a repair of your installation through Add/Remove Programs, it will repair any issues in your installation, including LiveUpdate.

Give that a go and see if this resolves your LU issue.

 

Laters!
