Confluence attachments file storage limit

Hello All,

Could any one guide how i can see the default confluence server files storage limit?

Do we have any kind of upgrade option where we can increase the storage limit.


Currently i am using below confluence version:

Confluence 6.3.3

Hi @HiteshS,

  Are you referencing the attachments directory size on the server or an actual file which is larger than 100mb? Opt/attachments is where the bulk of your attachments will live so you will want to allow enough space for future growth.

For files: To change the max attachment size allowed for uploading, follow the link @Brant Schroederposted. Here is a direct link to the configuration change page:

Thank you Smith.

but i am looking for overall confluence server storage limit. I found one link here which shows that if users are 0-500 then 25 GB will be and if Users are 500+ then 100 GB (combination of JIRA and confluence both).

@HiteshS We are at 2000 users with 80GB opt/attachments directory. Since we host the solution, there really isn't a max number: It all comes down to hardware limitations and pricing of memory. Once we hit 90% capacity, we increase storage and plan for future growth.

@Brant Schroeder 's link above notes the following:


..... for overall storage capacity, it depends on your hardware specifications and storage configurations.

Here, 2000+ users and 800G+ attachments ... and don't know the limits

We will expand storage to 3T right now
