Help with cache files

Question

I am extremely new to Avamar, as you can tell from the quesitons:

So I have a bunch of linux VMs I backup that /var is not big enough to support the cache files Avamar creates.

So I have some questions if you do not mind.

1) is there a way to move the location that the cache file reside.. currently the default seems to be: /var/avamar

2) Can I delete the cache file, if I do what would be the impact of future backups? will they recreate them?

3)How do I create excludes filesystems within Avamar for a linux VM?

4) Why is there a f_cache2?

Thanks

David

EXAMPLE OF MY CACHE FILES:

I assume F_* is for filesystem level and the other is for image level?
-rw-r----- 1 root root 181949440 Oct 16 18:01 f_cache2.dat

-rw-rw-rw- 1 root root 5767712 Sep 20 18:02 f_cache.dat
-rw-rw-rw- 1 root root 1573408 Oct 16 18:01 p_cache.dat

I have found a doc that a person has attached to another question in the community:

Best practice PDF is what I was reading..

It mentioned how the file doubles each time..

The issue we are seeing is the cache file on a 8GB VM is getting past 5GB in size.. This is killing us and I need advice on how to deal with it as it is filling up /var

so you have linuxVM's but you are backing them up a physical servers - meaning you have installed the Avamar client on them and are not backing them up as vmdks....

I am doing the same.

with unix you can create links...

so on my servers /var/avamar is actually a link to /opt/avamar

where/opt is a seperate Logical Volume on the server - one that is not related to the root FS so it will not affect root if it gets full.

and as /opt fills up I can just add more space to that drive on the vm

so pick a dir in a different volume group and move /var/avamar over there

then make a link from /var/avamar to your new location.
