/usr/bin/ln Argument list too long

[Thorlake]

Hi guys,
Sorry for bothering
By any chance is there a way to help me?

For version

prodrigestivill/postgres-backup-local:14

and configuration

  POSTGRES_EXTRA_OPTS: -Fd -Z9 --schema=public -b
  SCHEDULE: 0 12 * * *
  BACKUP_KEEP_DAYS: 9
  BACKUP_KEEP_WEEKS: 0
  BACKUP_KEEP_MONTHS: 3
  BACKUP_KEEP_MINS: 0

I got the exception

./backup.sh: line 105: /usr/bin/ln: Argument list too long

I assume the code from https://github.com/prodrigestivill/docker-postgres-backup-local/blob/main/backup.sh#L105

ln -f "${FILE}/"* "${DFILENEW}/"

just links folder /last to currently created folder. However there are maybe too many files and ln can't be executed

file name is usually something like

/backups/daily/superuser_db-20240822.sql.gz/3419.dat.gz
/backups/daily/superuser_db-20240822.sql.gz/3420.dat.gz
/backups/daily/superuser_db-20240822.sql.gz/3431.dat.gz
....

What is the best way to fix it?
To fix project code to sth like

for f in "${FILE}"/*; do
  ln -f "$f" "${DFILENEW}/"
done
```
same for WFILENEW and MWFILENEW

upd: checked and I do have really a big number of files like `-20240902-100510.sql.gz/blob_17240.dat.gz'`
because number of blob files is huge (with directory custom dump type)

This is clearly a bug, thanks for reporting!

I will try to fix as soon as I can.

I close this discussion but we can continue at #157.
