Full backup of folder failed

Thread needs solution

After 2-3 years of trouble-free backing up using Acronis True Image v10 – Build 4942 (OS Windows XP SP3), I have attempted and failed several times to start a new Full Backup of my Photos folder (size 89.2Gb) . The backup started but stalled – and stayed stalled for several hours until manually stopped. The backing up stopped at different times with the different attempts – any thing between 20% and 60% completed.

I am backing up to a folder on an external hard disk (Western Digital, MyBook 500Gb) connected via Firewire. I checked the hard disk using Chkdsk and it passed with no errors reported – although the Phase 4 process did take a long time and did not proceed smoothly. I also used the diagnostic tools provided by Western Digital and again the disk passed.

There were no errors reported in Device Manager.

I defragmented the external hard disk but the backup still failed.

The external disk has sufficient free space (~160Gb) for the back up

The file of the aborted backup was labelled “PhotosBackUp#8_1.tib”. In setting up, I had requested “PhotosBackUp#8_.tib”. All previous full backup files have been labelled as requested (i.e. without “1”) and incremental backups based on the full backup are named “PhotosBackUp#8_2.tib, PhotosBackUp#8_3.tib …..etc.). I have not seen a file labelled with “1” previously.

No errors are reported in the TI log nor were any pop-up warnings shown during the attempted backup.

Incremental backups of other folders on my system to the same external disk (albeit to a different folder) are still working OK.

Validation of the previous photos archive backup, which included 14 incremental backups, still succeeded – taking approximately 1.5 hours.

I should be grateful for any advice on how I can run another full backup of my Photos folder.

Something must have changed after those 2-3 years of successful backups. Is it the same external drive in use?

But think about this ... there was another user here not more than a week ago who lost years of photos because of True Image. There is another much safer alternative to backing up photos, music, mp3's etc. Many of the regulars here would recommend something like Karen's Replicator or Microsoft's Sync Toy, both are free. Both keep the backup in their native format and once the initial backup is made, only changed and new photos will be backed up so the process goes much quicker. If you're using True Image because of it's compression remember that photos are already in a compressed format so nothing will be gained by trying to compress it further.

Thanks for comments DwnNDrty.

Not sure what has changed - certainly all hard disks are the same as when last ran a full backup successfully.

I take the point about perhaps using a method other than TI for keeping a backup of photos. Just that TI had been so reliable and convenient - until now!

I would like to know why I now have the problem with TI because I need it for backing up other folders that will benefit from compression.
