If 2 processes are accessing the same folder this looks for me that this may screw up the correct version history and may corrupt the backup. I am not sure which role this folder plays, QNAP staff told me that this folder is needed to get the versioning correct. find reveals that there are 57868564 files in the folder.du reveals that 2.5TB are in the folder.Settings -> shared folders -> edit properties and untick „Enable Network Recycle Bin“ To get rid of the power_clean issue, you can just disable the folder: Putting all this together I would assume that 90% of the load created by my TS-231P is absolutely useless. It has at least the size of the source files which should be backed up. VersionRecycle folder is created and deleted with each backup cycle. Our old friend the „.VersionRecycle“ folder is also in the folder. 10 15 * * * /usr/bin/power_clean -c 2>/dev/nullĪccording to the lsof command the power_clean command scans through the complete folders in the folder. It is not even possible to let the cleanup job run fewer than once a day (only by manipulating the crontab but not sure if it’s overwritten by QTS). But that’s not the point: In the network options there is a cleanup job for the folder which runs every day: It means that the space used by these files is still occupied. The files from the backup should be deleted (according to my options which I set in the RTRR job) and not just moved into another folder. This is total nonsense (my point of view). The RTRR job intends to delete (old) files but the target NAS only moves them into the folder. If I wait for 3 hours before starting a new backup job the folder is deleted completely. VersionRecycle folder while the new backup job recreates the same folder. If a second backup jobs starts an hour later the „rm“ command still deletes files in the. This took 3 hours in my case.īoth devices show that the backup job finished successfully, the NAS is ready to start the next backup job because no background task is shown. Hybrid Backup Sync optionsĭuring the runtime of a backup, a „rm“ (remove) command is started on the source NAS and tries to delete a folder called „.VersionRecycle“ (~1TB).
Both devices are in my local network connected by a 1Gbit/s connection. I am using Hybrid Backup Sync (HBS) to perform a backup from one NAS to the other.
