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.
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
