How do you know GC is clearing off data? How much is it clearing off?

Run the following:-

grep "Elapsed time\|Total bytes" /usr/local/avamar/var/cron/gc.log | tail -30

It will grep out the amount of data removed and how long GC is run.

Regardless if it is full you proabley want to conact support and get Agressive GC setup. It means the server will be down for a few days but if it is fully you will not be able to do backups regardless.

Another point that needs to be considered is that due to de-duplication only chunks that are unique to the client that has been deleted and not used by any other backup will be removed by garbage collection.

In any case, if the server is 100% utilised, GC has problems in clearing space. Contacting support would be the best bet.

Thanks for your answers. Below the result of grep "Elapsed time\|Total bytes" /usr/local/avamar/var/cron/gc.log command.
The deleted client server is an Enterprise Vault server (mail archiving), so it contains lots of unique files. The first backup took around 800Go and new bytes were 95%, so a lot of space should be freed, no ?

You can see from the output that GC is only run for 24 mins a most, even by defalt GC will run for 1 hour if it has data to remove and it is only moving 1.7 Gb at a time. So I think Goran may be correct and GC is just not finding much to remove.

But as Hari and myself has said contact support - you should not try to deal with this stuff on your own - support has a lot of expericen with this, capcity issues makes up a high proportion of support calls.

No because with dedupe it's all about unique chunks and not files. Avamar doesn't care about files.

From what has been said so far, it's time for you to call a support.

May I know which data are share with other client? I mean , I delete or change de Retention, Hope to decrease storage space in avamar node, but as I know the de duplication share this data with other clients, do i have the possibilty to know wich are the other clients who is shared this data?

Summary:

I change retention in one of my top 3 high clients and no decrease the storage as I hope

Total indexstripes=3206

indexstripes processed= 1344

Some one can explain me in detail what exactly are the indexstripes? and if this configure can reduce my storage when i run a GC?

Regards

You said you deleted the "client" Did you also delete all the backups associated with the client. Just removing a client does not alos remove all the historic data that Avamar backed up from that client. You need to go into backup mgmt and select the client then delete all associated backup. Then just let the gc run.
