Storage Cleanup (Garbage Collection)¶
SeaTable uses storage de-duplication technology to reduce storage usage. The underlying data blocks will not be removed immediately after you delete a file or a base. As a result, the number of unused data blocks will increase on SeaTable server.
To release the storage space occupied by unused blocks, you have to run a garbage collection program to clean up unused blocks on your server.
Use Ofelia to enable scheduled garbage collection
You can add Ofelia to your SeaTable deployment to run the garbage collection process on a configurable interval. This ensures that any unused data blocks will be automatically cleaned up.
Configuration¶
Add the following lines to seafile.conf to keep deleted files for only 60 days:
[history]
keep_days = 60
Dry-run mode¶
To see how much garbage can be collected without actually removing any garbage, use the dry-run option:
docker exec seatable-server /opt/seatable/scripts/seatable.sh gc --dry-run
The output should look like:

Removing Garbage¶
Run a garbage collection program without adding --dry-run option to actually remove garbage block.
docker exec seatable-server /opt/seatable/scripts/seatable.sh gc
