Unable to delete backups older than x days

we have a requirement to delete the backups which are older than 10days. I have scheduled it in cronjob, but its not happening.
[mongod@tora-pl211 ~]$ pbm cleanup -y --older-than 10d --wait
nothing to delete

Please let me know if any other command to replace it.

Hi Aranjith,
What version are you using? For 2.0.5 and older, you should use a timestamp argument to the older-than flag:

For PBM version 2.0.5 and earlier, use the pbm delete backup --older-than <timestamp> command. 
You can configure a cron task to automate backup deletion by specifying the following command in the crontab file:
$ /usr/bin/pbm delete-backup -f --older-than $(date -d '-1 month' +\%Y-\%m-\%d) 

Hi @Agustin_G , we use percona v2.2.1, this version has new feature to delete the backups older than x days irrespective of PITR backups.
my question is why the command “pbm cleanup -y --older-than 10d --wait” doesn’t work in this version.

In older versions(say 2.0.x), we use “pbm delete backup --older-than ” command. but this requires to manually delete pitr first .

pbm cleanup command is not working in this version2.2.1.
see below:

[mongod@tora-pl211 ~]$ pbm list

Hi @percona ,
Can someone please help, is there a alternative command to delete the backups.

[mongod@tora-pl211 ~]$ pbm cleanup -y --older-than 15d --wait
nothing to delete
[mongod@tora-pl211 ~]$ pbm delete-backup -f --older-than $(date -d ‘-15days’ +%Y-%m-%d);

I believe in recent version, not needed to delete pitr first.
